But its experience developing maintenance procedures for ITER components using remotely controlled robots will now be applied to a wider scope of applications, including industrial maintenance and health care. MIT graduate student contributes to the understanding of plasma heat transport. A team led by MIT professor Anne White, Cecil and Ida Green Associate Professor in the Nuclear Science and Engineering Department, and Pablo Rodriguez Fernandez pictured , a graduate student in the Department of Nuclear Science and Engineering, has conducted studies that offer a new take on the complex physics of plasma heat transport, and point toward more robust models of fusion plasma behaviour.
To make fusion energy a reality, scientists must harness fusion plasma, a fiery gaseous maelstrom in which radioactive particles react to generate heat for electricity. But the turbulence of fusion plasma can confront researchers with unruly behaviours that confound attempts to make predictions and develop models. In experiments over the past two decades, an especially vexing problem has emerged: In response to deliberate cooling at its edges, fusion plasma inexplicably undergoes abrupt increases in central temperature.
These counterintuitive temperature spikes, which fly against the physics of heat transport models, have not found an explanation—until now. This is what makes investment in science like fusion energy research so powerful—the impact extends well beyond the laboratory.

You can download the brochure here. The chemical element lithium may just have found itself a new application. These instabilities are known as edge-localized modes ELMs and occur at the outer parts of the fusion plasma. ELMs develop regularly when the plasma enters what is known as high-confinement mode, or H-mode, which holds heat within the plasma more efficiently. ELMs can damage the divertor, a plasma-facing component that extracts heat and ash produced by the fusion reaction, and cause fusion reactions to fizzle.
The researchers also found that it became easier to eliminate ELMs as the experiments progressed, possibly requiring less lithium as time went on. The results cause physicists to be confident that these techniques could also reduce ELMs in larger fusion devices that were designed to be compatible with lithium.
Burning Plasma Research. The Committee, operating under the auspices of the US National Academies of Sciences, Engineering, and Medicine, has been charged with reviewing the overall state of magnetic confinement fusion research in the United States. A key outcome of the review is to be a recommended strategy for going forward—with or without ITER—in a way that preserves the US status as a leader in burning plasma research.
The Committee publicly released its interim report on 21 December The main webpage for ITER news has evolved. Make it your bookmark today! The specialized installation will help scientists to test materials in an environment of neutron irradiation similar to that of a demonstration fusion reactor DEMO , the intermediate step from ITER to a commercial fusion reactor.
Research into materials with neutron-resistant properties is one of the key tasks laid out in the European Roadmap , Europe's guiding document to addressing the scientific and technological challenges on the way to adding fusion energy to Europe's future energy mix. A technical group of experts from both countries that evaluated both sides declared the Granada site as fully operational and acknowledged that construction works could start immediately.

Both centres open up opportunities for British industry. What causes a plasma to go from a weakly confined, turbulent state to a more defined and calmer state which is necessary for fusion to occur? Answering this question, scientists from the Princeton Plasma Physics Laboratory, the University of California and the Massachusetts Institute of Technology join forces to simulate tokamak plasmas.
With the help of a supercomputer located at the Oak Ridge National Laboratory ORNL called Titan, the research team uncovered for the first time the basic physics behind a plasma's transition into the high-confinement or H-mode. An issue of crucial importance is the right balance between the core temperature of a plasma and the temperature at its edge, which will have an effect on the size of the plasma. These simulations are of unprecedented scale. Only with such high-performance computing resources such as Titan involving over 18, graphic processing units GPUs and close to , central processing units CPUs , can problems of such great scientific complexity and importance be addressed.
The exchange covered the challenge of leading a multicultural project, the critical phase ahead as ITER begins assembly activities, and Bernard Bigot's conviction that there is nothing more exciting, more motivating, than contributing to a project that could change the course of civilization for hundreds of thousands of years. Excerpts below On managing one of the world's largest research projects: I accepted the Council's offer at a crucial moment in ITER history, when the project was entering into manufacturing and preparations for assembly.
This new phase required a new organization—one tailored to meet the double challenge of delivering an installation that is both a research facility and an industrial facility. What we needed at that point and need even more today was integration. ITER is a complex structure, with a central team here in France and seven "domestic agencies" emanating from the seven ITER Members that are responsible for the in-kind procurement of machine components and installation systems. To achieve this integration, we needed a clear, centralized decision-making process under the authority of the Director-General.
And all the while making safety and quality our highest priority. On striving for excellence in a multicultural environment: How do we achieve harmony and efficiency? Through mutual respect and the understanding that each culture has its own work habits, traditions and "best practices. The global world we live in has not erased national particularisms. But instead of seeing this as a problem, we see it as an asset: we are building a project culture in a way that takes advantage of the diversity of these "best practices" to achieve an optimal result.
You become Iternational Working at ITER is very demanding but it is also very rewarding. Can you think of something more exciting, more motivating, than contributing to a project that can change the course of civilization for hundreds of thousands of years? But like with any of these industries, the decision will be both technical and political and rest in the individual governments' and investors' hands.

The first presents results of research on plasma stability, in particular on instabilities in the plasma edge. The second item describes the use of a newly upgraded core turbulence microwave diagnostic system, known as correlation electron cyclotron emission CECE. Thanks to the CECE, plasma physicists will have a better understanding of turbulence in fusion plasmas. The extraction of the power produced in a future reactor poses one of the challenges in fusion research. In the ASDEX Upgrade the lower divertor is normally used for this purpose; now, scientists are investigating alternative configurations with a new, modified upper divertor.
The prize honours outstanding achievements in the field of plasma physics. The school provides courses on fusion energy, plasma experiments and related technology. It will mainly look at laser fusion and laser-matter interaction studies. Topics include plasma basics and fusion energy; inertial confinement fusion; magnetic confinement fusion; plasma-diagnostics; and technology. Registration is open until 20 March Interested participants are encouraged to give presentations. The deadline for submitting abstracts is 8 February For all related information please go to the Kudowa Summer School website.
One of the big challenges in developing fusion energy is controlling the plasma. Disruptions of the burning plasma can halt the fusion reaction and damage the walls of the fusion device. Scientists therefore are keen to learn how to predict plasma disruptions. They developed predictive software, the Fusion Recurrent Neural Network FRNN code, which is a form of what is called "deep learning"—a powerful version of modern machine-learning software.
Research team: William Tang, to the left; Eliot Feibush; and Alexey Svyatkovskiy, seated Drawing from data of the JET facility in the UK, the team has demonstrated the tool's ability to predict disruptions more accurately than previous methods. Turning their attention now to ITER, the team aims to improve the correct prediction of disruptions and reduce the number of false alarms. The deep learning software is also a challenge for computing hardware. The chair of the international program committee, Yutaka Kamada, and the chair of the international advisory committee, Yasuhiko Takeiri, both presented tributes.
The UK's nuclear fusion research program can expect a big financial boost. The new national fusion technology platform will open in It will enhance the UK's expertise in critical areas of fusion research and help British industry to secure contracts from ITER and other global fusion projects. It will also provide a powerful signal of the UK's intent to continue its participation in international science collaboration after leaving the European Union.
Taking a longer term view, the platform's two centres will help the UK to prepare the grounds for the first nuclear fusion power plants. It rewards outstanding researchers or companies who find new physics or technology solutions to address the challenges of fusion, with the potential of wider application. The competition is open to researchers, research teams and companies from around the world.
Anyone interested to enter the competition needs to apply through the Research and Innovation portal of the European Commission; the deadline for submissions is 8 March An independent jury of experts in technology transfer will select the three winners and the award ceremony will take place as part of the 30th SOFT conference taking place in Giardini Naxos, Sicily, Italy, from September.
Last year's winners were awarded the prize for a novel type of high temperature superconductor cable based on REBCO tape material, a new membrane technology to produce ultra-pure hydrogen and a new virtual reality software technology to improve radioprotection. SOFT is an important conference in the area of fusion technology and research in Europe. It attracts over scientists, engineers, industry representatives and exhibitors from around the world.
This explains the nonlinear dependence of the L—H threshold power on density and enables the derivation of a general expression for the density minimum.

It is a hot, electrically charged gas and the most abundant form of visible matter in the universe. Some 99 percent of the known universe is in plasma state. Plasma can also be found on Earth such as in lightning and fluorescent light bulbs. Read more about the journal and its new editor-in-chief. Their aim was to get first-hand information on the current status of the ITER Project to allow member states to respond to the Commission. Thirty-four delegates from 18 states plus Switzerland participated. The request was based on the Commission's positive assessment of the changes in the overall management of the ITER Project and the completion of important milestones in the preceding two years.
MAST is about to undergo a baking operation in order to clean the interior surfaces of the vessel and enable the ultra-high vacuum required for operation. Read more about the operation on the CCFE website. Fourteen authors and one illustrator share their passion for fusion in special October issue of Fusion in Europe.
What is also special about the issue is that most of the authors are students or young researchers from around the world. The newsletter is thus a window onto the views of the next generation of fusion professionals and enthusiasts. A major challenge in the development of fusion energy is maintaining the ultra-hot plasma of a fusion device in a steady state, or stable form. While superconductors can allow a fusion reactor to operate indefinitely, controlling the plasma with superconductors presents a challenge because engineering constraints limit their response time compared to the more energy consuming copper coils.
The slower pace makes it difficult to operate a stable discharge with the large plasma volume or extended vertical height required for producing fusion power.

Its superconductors are made of niobium and tin, the same conductor that is planned for use in ITER. The successful control method, demonstrated this summer by Mueller and physicists from the National Fusion Research Institute NFRI in South Korea, which operates the tokamak, and General Atomics in San Diego, caps years of effort to control the vertical instability, which had allowed the plasma to bounce up and down in the foot-high vacuum vessel.
See how they did it in the full article on the PPPL website. It is inscribed in bold letters on the large poster that is affixed to the ITER Assembly Hall: harnessing fusion energy is akin to "bringing the power of the Sun to Earth. The fusion reaction in our machine, however, is not like that which occurs in Sun-like stars. Although the end product helium and the ingredients hydrogen isotopes in one case, hydrogen in the other are the same, the nature of the process is profoundly different. An international team of fusion experts working at the DIII-D National Fusion Facility in San Diego, California, has discovered a way to minimize the effects of a phenomenon that can decrease the performance of fusion reactors and even possibly cause damage to the device.
With no heating top , upward frequency sweeping RSAEs are observed. With heating near the wave location bottom , no RSAEs are expected or observed. Adapted from: M. Van Zeeland, W. Heidbrink , S. Sharapov , D. Spong , A. Cappa, et. Fusion 56 , Titled "Is Fusion the Fuel of the Future? You can read the article on line at Energy Focus pp See more on the "Positive Energy" website. For hydrogen atoms to fuse into helium, the heat of the ultrahot plasma in the tokamak must be maintained.
What is phishing?
But, like boiling water, plasma has blobs or bubbles that percolate within the plasma edge, reducing the performance of the plasma by taking away heat that sustains the fusion reactions. The simulations, produced by a code called XGC1 developed by a national team based at PPPL, performed kinetic simulations of two different regions of the plasma edge simultaneously. This ability produces a more fundamental and fuller picture of how heat moves from plasma to the walls, potentially causing damage. Blobs play an important role in the outward movement of particles in plasma. Blobs cause approximately 50 percent of the particle loss at the plasma edge, and researchers have observed blobs in a wide range of plasma devices, including tokamaks, figure-eight-shaped fusion devices known as stellarators, and linear machines.
Churchill said. Researchers led by the Princeton Plasma Physics Laboratory PPPL have proposed an innovative design to improve the ability of future fusion power plants to generate safe, clean and abundant energy in a steady state, or constant, manner. The design uses loops of liquid lithium to clean and recycle the tritium, the radioactive hydrogen isotope that fuels fusion reactions, and to protect the divertor plates from intense exhaust heat from the tokamak that contains the reactions. The lithium, a silvery metal that readily combines with other elements, would serve a number of functions, including protecting the divertor plates, capturing tritium for recycling, and removing dust and other unwanted elements.

If we were to use only conventional nuclear energy to power the world, we would need to consume approximately 7, tonnes of nuclear fuel enriched uranium or mixed oxyde. Forbes magazine has a detailed article on this topic here. Following the commissioning of its sub-systems, WEST has had a short shutdown period during which the ICRH antenna was installed and other machine optimization activities carried out. Plasma experiments should resume in October.
Data collected throughout the experimentation will help engineers optimize the sensors' final design. Read the full story on the European Domestic Agency website. It was against the backdrop of the magnificent National Museum of Natural History where "Let there be Light" celebrated its most recent success by opening the edition of the Pariscience Film Festival.
More than guests, among them many film-producers and journalists, had gathered in the historic amphitheatre to watch the award-winning minute documentary on fusion energy produced by Canadian director Mila Aung-Thwin and cinematographer Van Royko. For most of the attendees, the film had been the first contact with the ITER Project and so the crowd was curious to learn more about the international quest for fusion energy.
The applause at the end paid tribute to an entertaining evening and—as many professional film producers attested—to an outstanding film. On board are 85 tonnes of aluminium DC busbars and system components, part of an overall procurement package that includes some 5 kilometres of busbars tonnes as well as fast discharge units and switching networks. The biggest are designed to carry close to 70 kiloamps of current to the 18 toroidal field coils of the machine; others will connect to the poloidal field coils, correction coils and the central solenoid.
The first two batches of equipment were delivered and and , and more are expected. The leadership change comes as PPPL moves forward with the recovery phase of the NSTX-U spherical tokamak, which encountered a malfunction in one of its magnet coils in The lab is constructing prototype magnets in preparation for replacing the one that failed last year, as well as five others that were built under similar conditions. The spotlight turned this summer to this recent member of the worldwide tokamak community, as Kazakhstan hosted the World's Fair. Kazakh Journalist Grigory Bedenko has visited the KTM Tokamak in Kurchatov, where commissioning operations are underway in preparation for the start of operations next year.
See his long photo reportage here. The Russian Domestic Agency—responsible for supplying four test stands for the vacuum, heat and functional testing of the port plugs before their installation on the machine—has contracted with the Russian firm Cryogenmash for the development of the technology. Vacuum and leak tests were run recently with results that surpassed expectations. The latest podcast from Decrypted by Bloomberg starts with the question: "How close are we to realizing the silver bullet for clean, cheap and abundant energy PPPL physicist discovers that some plasma instabilities can extinguish themselves.
Physicist Fatima Ebrahimi from the Princeton Plasma Physics Laboratory PPPL has for the first time used advanced models to accurately simulate key characteristics of the cyclic behaviour of edge-localized modes ELMs , a particular type of plasma instability. The findings could help physicists more fully comprehend the behaviour of plasma, the hot, charged gas that fuels fusion reactions in doughnut-shaped fusion facilities called tokamaks, and more reliably produce plasmas for fusion reactions. The findings could also provide insight into solar flares, the eruptions of enormous masses of plasma from the surface of the sun into space.
ELMs occur around the outer edge of high-confinement, or H-mode, plasmas due to strong edge currents. The model demonstrates that ELMs can form when a steep gradient of current exists at the plasma edge. The gradient develops when the plasma moves suddenly up or down, creating a bump in the current and forming an edge current sheet. The instability then forms a current-carrying filament that moves around the tokamak, producing electrical fields that interfere with the currents that caused the ELMs to form.
With the original currents disrupted, the ELM dies. The research could also improve understanding of solar eruptions, which are accompanied by filamentary structures similar to those produced by ELMs. Her next step will involve investigating the impact of differences in plasma pressure on the cyclic behaviour of ELMs. This phase—which involves the three manufacturers plus a fourth, pre-qualified supplier—is expected to last approximately three years.
Dr Shimomura will be remembered by his many friends and colleagues in the ITER community as a gifted physicist who contributed greatly to the project during an involvement spanning 20 years. He will be greatly missed by all who knew him and who benefitted from his leadership and guidance. In ITER, six technological solutions for tritium breeding—in the form of test blanket modules plus associated ancillary systems—will be operated and tested for the first time.
Their experimental validation will represent a major step for fusion development beyond ITER, when tritium fuel will necessarily have to be bred within the reactor. Europe is developing two types of test blanket modules, which consist of a steel box containing tritium breeders, neutron multiplier materials and heat extraction plates.
Over the past two years, the European Domestic Agency and industrial partners have been manufacturing mockups of these boxes to test welding techniques. A preliminary welding procedure, employing a tungsten inert gas TIG welding robot to carry out the tasks within the limited space of the box, has been identified. The welding qualification cycle is expected to end within the next two years. See the full article on the European Domestic Agency website.
Synakowski will also be a professor in the university's Department of Physics and Astronomy. The role of the vice president for research and economic development is to support and facilitate the research efforts of University of Wyoming's faculty, staff and students; direct the university's research mission as a public research university; promote the university's research program with stakeholders; and direct technology transfer and commercialization efforts for the university's intellectual property.
His agency supports research at more than 50 universities, eight national and two federal laboratories, and 15 industry groups. At least miniature cameras will be installed inside the ITER machine to act as the eyes for operators charged with machine maintenance.
Some of them will give a wide-angle view of the inside of the machine; others will be embedded on the robotic arms used for repairs. By receiving live image from the cameras, engineers hundreds of metres away will be able to operate maintenance and repair equipment with extreme accuracy. The next step will be to develop a camera prototype. Specifically, the team has evaluated the heat-flux width at the divertor, or the width of the material surface that might sustain the highest heat load. Because the divertor directly faces the exhaust flow, it is bombarded with hot particles driven by electromagnetic fluctuations.
In ITER, in order to withstand the highest surface heat load, the divertor will be made of the toughest element on Earth: tungsten. Chang reports. Read the full report on research results at OLCF. The operation was successful: shortly after commissioning the first measurements demonstrated greatly enhanced spatial and spectral resolution for the temperature and density profile measurements of TCV plasmas. TCV is a variable configuration tokamak with highly specialized capabilities plasma shaping, versatile electron cyclotron heating, measurement, control systems for the exploration of the physics of magnetically confined plasmas.
Under contract with the European Domestic Agency, a team of experts has been working for more than a year to identify key technologies to perform the cutting and welding operations that will be required during the change-out of ITER divertor cassettes. The technical constraints are enormous—the work both cutting and welding will have to be performed remotely, the operational space is severely limited, and no lubricant can be applied as ITER is a nuclear environment.

Although plasma breakdown was routinely achieved, the ramping up of the plasma current was found to be difficult due to induced currents in the passive structures that have been introduced inside the vacuum vessel to produce the divertor configuration.
The vessel has been reopened to address stray magnetic field compensation through modification of the divertor baffle and a reduction in its electric conductivity to limit induced current. Experiments are expected to resume by the end of June. For fusion to generate substantial energy, the ultra-hot plasma that fuels fusion reactions must remain stable and kept from cooling.
They deployed lithium in the Chinese tokamak in three different ways: through a lithium powder injector, a lithium granule injector, and a flowing liquid lithium limiter FLiLi that delivered the element in liquid form to the edge of EAST plasmas. Good results were shown by all three techniques. Scientists from General Atomics also participate via a separate grant. Professor Kaw was a well-known and highly respected plasma physicist, author of over research publications in scientific journals. He was the founding director of the Institute for Plasma Research in Gujarat, India, which he led from to See the Institute for Plasma Research website for more information.
Deshpande, Head of the Indian Domestic Agency. Interested parties should contact Rob Akers at rob. Lithium compounds improve plasma performance in fusion devices just as well as pure lithium does, a team of physicists at the U. The research was conducted by former Princeton University physics graduate student Matt Lucia under the guidance of Robert Kaita, principal research physicist at PPPL and one of Lucia's thesis advisors, as well as the team of scientists working on a machine known as the Lithium Tokamak Experiment LTX. MAPP lets scientists analyze how tokamak plasmas affect a material immediately after the experiment ends.
In the past, scientists could only study samples after the machine had been shut down for maintenance; at that point, the vacuum had been broken and the samples had been exposed to many experiments, as well as to air. Lucia used the evaporation technique to coat a piece of metal with lithium, and then used MAPP to expose the metal to plasma within LTX. As he expected, Lucia observed lithium oxide, which forms when lithium reacts with residual oxygen in LTX's vacuum chamber.
He was surprised, however, to find that the compound was just as capable of absorbing deuterium as pure lithium was. Lucia's results are the first direct evidence that lithium oxide forms on tokamak walls and that it retains hydrogen isotopes as well as pure lithium does. They support the observation that lithium oxide can form on both graphite, like the tiles in NSTX, and on metal, and improve plasma performance. In the context of its Roadmap to the realization of fusion electricity EUROfusion , the European Consortium for the Development of Fusion Energy, has identified a number of crucial technical challenges that must be addressed through advanced research.
One of these is finding a viable solution for the heat exhaust in a future fusion reactor, considering that the divertor strategy planned for ITER cannot be extrapolated to a larger, steady-state facility. Late , EUROfusion called for proposals on plasma exhaust projects, which an independent panel of experts evaluated. The call, termed Plasma Exhaust PEX Assessment, received ten proposals that covered conventional and alternative divertors, as well as conventional materials and plasma-facing units as well as advanced materials. EUROfusion selected six projects for receiving support.

Scientists now have a better understanding of the factors leading to steel degradation and of the ways to improve the design and development of key components, such as the ITER breeding blankets—where tritium fuel will be produced from the interaction of fusion neutrons with lithium.
Following an initial run at the Wendelstein 7-X stellarator that lasted from December to March , a shutdown phase ensued to equip the machine for an operational campaign with longer discharges and higher heating power. Read about the complexity of these shutdown activities in the latest " Wendelstein 7-X Newsletter. Culham's new tokamak MAST Upgrade is to receive funding to tackle one of the hottest issues in fusion energy research—plasma exhaust.
The controlled exhaust of power and particles from a very hot tokamak fusion plasma, through the divertor area of the machine, is arguably the biggest challenge facing a future fusion power plant. Researchers at the U. The findings show that pumping more heat into the core of the plasma can drive instabilities that create plasma rotation inside the doughnut-shaped tokamak that houses the hot charged gas. This rotation may be used to improve the stability and performance of fusion devices.
The findings could lead to improved control of fusion reactions in ITER, the international experiment under construction in France to demonstrate the feasibility of fusion power. In order to master what's commonly refered to as "the energy transition," a diversity of energy sources need to be matched up in the energy system of the future — decentralized and centralized, weather-dependent and continuously operable units. The aim of the research project is to model the architecture for an environmentally compatible, efficient and stable energy system of the future.
Expected as new primary energy source in the second half of the century are fusion power plants, environmentally and climatically friendly facilities supplying about one gigawatt of electric power. The contribution of IPP will therefore be to work out the physical and technical properties of these devices — of either the tokamak or stellarator type.

After a very successful operational campaign, Helios was shut down earlier this year. The European tokamak JET is currently in an engineering shutdown phase. But shutdown doesn't mean inactivity—scientists are currently reviewing the experimental campaign and preparing for the next scientific program, which will include tritium-tritium operation followed by full fusion power experiments using deuterium and tritium in The JET remote handling team has taken advantage of shutdown to carry out a photographic survey of the vacuum vessel to inspect the condition of the wall, and to calibrate the detector that measures neutrons using the MASCOT remote handling system—a system allowing operators to undertake a wide range of tasks including welding, cutting, bolting, handling and inspection through a special manipulator that acts almost as the extension of an arm.
Deuterium is obtained from heavy water, which occurs in natural water at a concentration of just 15 parts per thousand. The heavy water is first isolated by a combination of chemical and physical methods, such as distillation, to obtain deuterium gas.

Every summer, the Max-Planck-Institute for Plasma Physics in Garching near Munich, Germany, organizes a one-week summer school in plasma physics for undergraduates. The course covers the main aspects of plasma physics with emphasis on nuclear fusion:. Two of the largest were delivered in November by the European Domestic Agency: metre quench tanks that will store gaseous helium in the case of a magnet quench.

For the past two years, Scott Silburn has been leading the development of Calcam, a program for calibrating camera viewing geometry on fusion devices. From this, the position, orientation, and lens properties of a camera system can be determined. This information can then be used to calculate exactly where the camera's lines-of-sight pass through the plasma, and also which locations on in-vessel components correspond to which positions in the image.
An example application of the code is improved positional calibration for JET's high-resolution divertor infrared cameras, which measure the heat loads at the strike points where the plasma interacts with the divertor tiles. The improved information has been used to improve the accuracy of some of the signals from the cameras, and makes it easier to compare the camera data against other diagnostic signals. An agreable off-shoot of the technique is that it produces interesting images, as seen in the image above photo credit: CCFE.

The UK fully recognises the importance of international collaboration in nuclear research and development and we will ensure this continues by seeking alternative arrangements," the government said in the statement.
It is the only existing fusion device capable of operating with the deuterium-tritium fuel, which will be the fusion fuel of the future. Please see the full statement on the EUROfusion website. This school, held annually either near ITER or in one of the ITER Members, aims at preparing young researchers to tackle the challenges of magnetic fusion devices, and spreading the global knowledge required for a timely and competent exploitation of the ITER physics potential.
This year, the summer school will cover the physics of disruptions and control — one of the key issues for the ITER reactor and burning plasmas in general. Lectures and specialized seminars will cover current developments in theory and experiments, but are also intended to give the basics of the field. Poster sessions allowing participants to show their work are planned.
The ITER school will be a good opportunity for reviewing the recent progresses in this field and promoting the interaction between different branches of plasma physics, computational physics and applied mathematics. The course is open to PhD students and postdocs aiming to work in the field of magnetically confined fusion, as well as Master students in physics or engineering. Registration ends on 7 March For more information, please visit the website.
Five different editions have followed, focused on different subjects: in in Fukuoka, Japan magnetic confinement ; in in Aix-en-Provence, France plasma-surface interaction ; in in Austin, Texas Magneto-Hydro-Dynamics ; in in Aix-en-Provence energetic particles ; in in Ahmedabad, India radio-frequency heating , in in Aix-en-Provence high performance computing in fusion science ; and in in Hefei, China transport and pedestal physics in tokamaks. Could high-entropy alloys—a combination of different metals in roughly equal concentration—turn out to be THE material for fusion reactors?
The concept behind the creation of these alloys is ten years old and was first proposed by metallurgists. To date, the labs at Oak Ridge and the University of Helsinki have just combined two, three or four elements, whereas millions of possible combinations exist. See the report on the EUROfusion website. Overviews were given on different welding, joining and inspection techniques as well as the benefits and services available to ITER as corporate members of the TWI. Details of previous case studies carried out for both the ITER Organization and the European Domestic Agency were provided to demonstrate the large portfolio of services that can be called on.
Follow up meetings and initiatives on these and other subjects are anticipated to address the challenging, state of the art manufacturing processes required both at suppliers and on-site to enable the construction and assembly of ITER. The Ukrainian signatory is the Kharkov Institute for Physics and Technology KIPT , acting as coordinator for fusion research in seven national universities and research institutes. Fusion infrastructure in Ukraine includes two stellarators and two plasma accelerators, with particular expertise in the areas of plasma-facing components, materials, stellarator research and diagnostics.
The EUROfusion consortium coordinates work within the EUROfusion roadmap, which breaks down the path to the realization of fusion energy into specifically defined missions. Thirty research organizations and universities from 26 European countries plus Switzerland are now members; in addition about Third Parties contribute to the research activities through the consortium members. At the EAST tokamak in China, five Italian scientists recently joined their Chinese colleagues to participate in a week-long experiment aimed at testing a voltage-driven vertical stabilization system.
The new vertical stabilization system implemented and tested on EAST is identical to the one proposed for ITER, and these first tests show that it is compatible with the installation a new ITER-like multivariable shape controller for advanced configurations. The company manages all ITER logistics operations from a control room established in Marignane, France, close to the international airport that services the Marseille region.
A warehouse space of 12, m2 has been fully refitted for ITER component storage. A precise understanding of this edge region of the plasma—and accurate predictions of its behaviour—is one of the important topics of fusion research around the world. At the National Institute of Fusion Science NIFS in Japan, two researchers have succeeded in running a micro-level simulation of a plasma "blob" in the edge region by using their institute's Plasma Simulator supercomputer.
By marrying the supercomputer's computational capacity with a newly developed calculation program, they were able to calculate the movement of one billion particles. Their research results advance the understanding of the behaviour of the plasma edge and improve prediction accuracy. See the full article on EurekAlert!

The honour, given by directors of the research and educational foundation, recognizes "persons in the relatively early part of their careers who have shown both technical accomplishment and potential to become exceptionally influential leaders in the fusion field. The group's board of directors cited Gerhardt's "many scientific contributions," including his "recent work on predicting plasma disruptions, which will provide major benefit to ITER and other major fusion experiments, and the leadership you provided and are providing.
Even the greatest performers need rehearsals Scientists and engineers at the world's largest operating tokamak have been preparing for JET's next starring role — a run of tests using the high-power fuel mixture of deuterium and tritium D-T. The deuterium-tritium combination is the one that will be used to gain maximum fusion output in ITER and in the first fusion power stations that will follow it. JET is the only present-day fusion machine that can use tritium and therefore has a vital role in preparing for ITER operations. As a radioactive substance, and one that is in short supply, tritium is not used very often at JET.
Most research is carried out with deuterium only the last operations with tritium were in However new campaigns of both T-T and D-T experiments are planned in and to give the best simulation yet of how fusion plasmas will perform in ITER. The D-T rehearsal at JET during this summer and autumn aimed to simulate the operating environment for the tritium campaigns. With 13 years since the last tritium experiments, many of the systems and the people working on them have changed. The rehearsal was an ideal opportunity to test procedures for using tritium, train staff and iron out any flaws ahead of the real thing.
Nine new researchers seven PhD positions and two postdoc positions will be recruited to work in an integrated approach together with DIFFER's existing scientific staff. A key experiment in the program is DIFFER's linear plasma generator Magnum-PSI, the only laboratory facility in the world capable of examining materials exposed to the intense plasma conditions at the walls of future fusion reactors. In addition, the team will test their research at existing fusion experiments in Germany, Switzerland and the UK.
The water detritiation system at ITER will remove tritium from process water during plant operation and recycle it as fuel. See the news here. For the first time in twenty years, a tokamak will experiment with nuclear plasmas. Equipped with an actively cooled tungsten divertor and additional power, experiments at WEST will provide precious data on operation in a tungsten environment in advance of ITER operation. Considerable modification to the machine's internal elements has been carried out. New components have all been installed in the vacuum vessel divertor coil windings, protection panels, antennas, diagnostics, tungsten plasma-facing components and the chamber has now been closed for final commissioning before plasma operation.
The experimental campaign at the JET tokamak, Europe's flagship device, came to an end on 15 November with nearly all goals met, according to a recent article published on the EUROfusion website. JET will restart operations in Read the full article on the EUROfusion website. Schulz GmbH in Germany for the procurement of piping materials.
The scope covers up to 65 km 1, tonnes of pipes and 43, units tonnes of fittings. The first shipment of pipes and fittings under this contract was delivered late October to the ITER worksite. Thirty-three tonnes of material were delivered, including metres of stainless steel seamless pipes and stainless steel fittings such as tees, elbows and reducers. The material will be stored in ITER's largest warehouse on site until needed for installation. At , frames per second, the movies from the MAST device give a vivid illustration of how tokamaks keep fusion fuel trapped in a magnetic cage, with particles moving around magnetic field lines and resembling a large spinning ball of wool.
If only it were that simple; in reality, a magnetically-confined plasma is a highly complex system, and predicting how it behaves is key to making nuclear fusion a viable energy source. In particular, knowing how the hot fuel affects the cold walls of the machine is integral to ensuring that future reactors survive.
Turbulence in the magnetic field throws out wispy bunches of particles—known as filaments—from the plasma in a seemingly random fashion, ejecting fuel which touches the surfaces of the tokamak. Researchers are now working to unravel meaning within this randomness to understand this complex interaction with the machine walls, and videos such as these can give them pointers to what is happening. Seeing the MAST plasma at this unprecedented level of detail enables us to image individual filaments and measure their size, velocity and position within the plasma.
It tells us a lot about their physics so we can find out how to predict their motion and, in future experiments, possibly learn to control them. In his new role as chair he will provide policy oversight and support to the journal's editor. Europe is responsible for the largest portion of ITER construction costs Important results included increased pulse duration and maximum magnetic field strength; achievement of the optimum H-mode regime; success in reducing plasma instabilities through a second neutral beam injector; and commissioning all magnetic diagnostics.
