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.

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.

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.
