Australian-born physicist Peter Thonemann died on 10 February 2018 at the age of 100. Thonemann was the leader of the ZETA fusion project when in 1958 it was famously—and wrongly—declared that it had achieved nuclear fusion.

Thonemann, whose family descended from German emigrants, was born in 1917 in Melbourne, Australia. To pursue an academic career in physics, he moved to Oxford, England, in 1944 and became one of the early researchers in nuclear fusion. As head of fusion research at Oxford and later at Harwell, England, Thonemann played a key role in the Zeta fusion project at the time when it made international headlines.

In January 1958, the announcement that the Zeta toroidal fusion device had achieved nuclear fusion was greeted with great enthusiasm. Less than four months later, the British scientists leading the project had to retract their earlier pronouncements. Although fusion research initially suffered from this setback, the Zeta episode helped drive the secrecy out of nuclear fusion research and create the foundation for scientific cooperation in this field across national boundaries.

Thonemann moved on to become deputy director of the Culham Laboratory in the mid-1960s, today home of JET, the Joint European Torus. A few years later, in 1968, he became professor for physics at what is today the University of Swansea, Wales. Late in life, Thonemann turned his scientific curiosity to biology and conducted research on the E. coli bacterium.

Taiyô Tenno is a young Japanese student on a world tour of "art masterpieces"; Soléane is "a scientist at heart," presumably French, who speaks perfect Japanese. They meet at Cézanne's workshop in Aix-en-Provence and soon find themselves seated at the terrace of Les Deux Garçons, the town's most elegant café.

Soléane speaks Japanese because her work in "energy research" implies a lot of "professional dealings with Japan." Taiyô Tenno is impressed, especially when Soléane explains that her work is about "duplicating the energy-generating process in the Sun and stars"...

The first manga on ITER—"A small sun on Earth"—has just been published by ITER Japan and is available in Japanese, French and English.

The International Zvenigorod Conference on Plasma Physics and Controlled Fusion is an annual rendezvous near Moscow for fusion research specialists from Russia and abroad. For one week in April, recent achievements in high and low temperature plasma research, the field of controlled fusion, and the development of plasma and beam technologies are presented through lectures, short talks and poster presentations.

Russian participation in the ITER Project was reported at the "ITER Project: Step to future energy" portion of the program under the direction of Anatoly Krasilnikov, director of the Russian Domestic Agency. Representatives of the research centres and the industrial companies involved in the procurement of ITER systems and components were present to report on the challenging technical specifications of the packages under Russian responsibility and the benefits of participation in ITER for the Russian research infrastructure overall.

Drawing inspiration from the robotic tasks that will be faced at ITER during installation and maintenance activities, the annual ITER Robots contest challenges students of different ages to imagine, design, and program Lego robots. Launched in 2012 by Agence Iter France and the ITER Organization, the program is growing every year.

As Newsline reported last June, the 2017 ITER Robots competition involved 600 students from 27 schools organized into 46 teams. This year, the competition will expand to about 70 teams and also offer a new program—ITER Robots Junior—for primary age students in 4th, 5th and 6th grade (12 additional teams). And who better to help design the new junior competition than 14-year-old Camylle Jordan, who spent one week as an intern in ITER's Remote Handling Section.

According to Jean-Pierre Martins, the ITER remote handling engineer who supervised Camylle, "she solved every issue she encountered in a pragmatic manner." In addition to becoming familiar with the complexity of the ITER Project, Camylle had to adapt her programming skills to work with a Thymio robot and to learn the basics of SolidWorks ®, a Computer Assisted Design tool.

The young intern left the ITER engineers impressed with her efficiency and confidence. She successfully tested the proposed curriculum and competition design, proactively suggesting and demonstrating ways to improve the robot mission. She participated in the official kick-off meeting of the ITER Robots Junior challenge, interacting with people from ITER, Agence Iter France and the French education system (Education Nationale). And she found time to fit in a tour of the ITER worksite and virtual reality room, and to give an on-camera Facebook interview to student journalists.

Most importantly, she documented her progress systematically, keeping a logbook of written records, photos, and videos, to ensure the contribution of her workweek at ITER would not be lost.

A research team at Princeton University has succeeded in significantly improving the quality of disruption predictions for a plasma in a tokamak fusion device through deep learning.

The team led by plasma physicist William Tang had access to the database of the Joint European Torus (JET) tokamak to demonstrate the potential of deep learning and neural networks in the analysis of large amounts of plasma disruption data. They fed more than a half-petabyte of information into their fusion recurrent neural nets (FRNN) deep learning software.

Through GPU-accelerated computing—i.e., the use of a graphic processing unit together with a CPU—disruption prediction improved dramatically in accuracy and speed. The Princeton team also demonstrated the scalability to over thousands of even more advanced GPUs.

According to Tang, this development holds a huge potential for accelerating scientific discovery through deep learning for fusion research.

The Massachusetts Institute of Technology (MIT) has just released plans for a number of initiatives that will broaden its engagement in fusion research.

MIT has been a long-standing player in fusion research, receiving support primarily from the US Department of Energy that has included funding in three major experiments at MIT's Plasma Fusion and Science Center (PFSC). The last of these—the Alcator C-Mod tokamak—ended operations in 2016 after 23 years and approximately 33,000 plasma shots.

Now, in a renewed approach, researchers at MIT will be working with a newly formed company, Commonwealth Fusion Systems, to combine the experience of a well-established lab with the more nimble and longer-term financing perspectives from the private sector.

Commonwealth Fusion Systems is an independent, for-profit company created by former MIT staff and students for the accelerated commercialization of fusion energy.

Joint teams will be working to develop a new class of high temperature superconducting magnets, followed by the conception and construction of a compact 100 MW fusion experiment called SPARC, and finally a larger demonstration power plant. 

Commonwealth Fusion Systems has obtained $50 million in funding from the Italian energy company Eni, which is also a founding member of the MIT Energy Initiative (MITEI). Eni has also announced funding to the order of $2 million per year for PSFC's newly created Laboratory for Innovation in Fusion Technologies, which will focus on cutting-edge solutions for some of the challenges on the road to a steady-state fusion reactor.
