Researchers led by CS Chang of the Princeton Plasma Physics Laboratory (PPPL) have been awarded major supercomputer time to address key issues for ITER. The award, from the DOE's INCITE* program, renews the third and final year of the team's supercomputer allocation for the current round.

The third-year allotment consists of 1.5 million node hours on the Theta supercomputer at the Argonne Leadership Computing Facility, and 0.97 million node hours on Summit, the world's most powerful supercomputer, at the Oak Ridge Leadership Computing Facility. Since every computer node has thousands of processing cores, or data processors, a single node hour equals thousands of core hours.

The INCITE announcement of the renewal called the studies "time-urgent for the successful planning of ITER operation" and ones that require "an intensive, concentrated computing effort using extreme-scale supercomputers."

The multi-year project studies three high-priority ITER edge-plasma challenges: gauging the heat-load that will strike the material surrounding the plasma in ITER; understanding the physics behind the transition from low-to-high ITER plasmas; and, studying turbulence at the edge of ITER plasmas that could damage the interior of the fusion facility.

*Innovative and Novel Computational Impact on Theory and Experiment (INCITE)

The offices of the ITER Organization will be closed from 23 December through 3 January included, although work will be proceeding on the construction site.

The year 2020 promises to be a special one for the ITER Project, as some of ITER's largest components arrive on site and the carefully orchestrated assembly phase for the ITER machine and plant officially kicks off.

Newsline will continue to cover every aspect of ITER and the fusion world, from progress on the construction site in southern France and in component manufacturing in factories and laboratories on three continents ... to meetings, conferences and scientific breakthroughs throughout the world.

See you in January.

From Wednesday 4 December 2019 through 28 January 2020 a public service announcement on ITER will be a regular feature on the Euronews network, which has a global reach of 430 million households (including 170 million European households) in 166 countries.

The goal is to raise awareness of the ITER Project, the promise of fusion, and Europe's leadership as the host Member—working together with China, India, Japan, Korea, Russia, and the USA—to bring to reality the most complex science experiment ever attempted.

The 20-second promotional spot has been filmed in five languages (English, French, German, Spanish, and Italian). It is scheduled to air two- to three-times daily, or approximately 70 times in December and another 70 in January.

You can watch the public service announcementson the ITER YouTube page in English, French, German, Spanish or Italian.

In the December 2019 issue of Physics Today (Volume 72, Issue 12), two physicists explore the ways in which ITER will be a major step in "bridging the gap between current understanding and the knowledge needed to design and operate fusion power plants as safe, sustainable energy sources."

Richard J. Hawryluk* (Princeton Plasma Physics Laboratory's associate director for fusion) and Hartmut Zohm (director at the Max Planck Institute for Plasma Physics, Garching) enumerate the open questions that are expected to be answered or clarified during ITER experimentation—heat and particle transport in the plasma core, stability of the edge region, plasma-boundary interactions, and alpha particle heating. "Experiments [at ITER] will be a unique opportunity to study burning plasmas, develop the tools needed to better understand them, and validate outstanding predictions. The experiments will provide seminal answers to questions that are central to the prospects for fusion."

Significant fusion power has only ever been achieved in two devices—and only for a little less than one second: up to 10 MW in the Tokamak Fusion Test Reactor (US), and up to 16 MW in the Joint European Torus (UK).

ITER—with the capability to produce 500 MW of power for more than 300 seconds—will enable "the first in-depth study of burning plasmas in a magnetic confinement configuration."

Fusion science and technology are complex matters that are difficult to explain to non-specialists. In its fall edition, Fusion in Europe (published by the EUROfusion network) asked a dozen "fusioneers" to write about the challenges they face in their daily practice. Whether hard-core scientists working in European laboratories and institutions, teachers or PhD students, they all volunteer their time to "entertain, enthral and educate" the general public.

"How do we teach ten-year-old students a complex topic like fusion?" asks Patricia Raposo-Weinberger, who teaches at Graz International Bilingual School in Graz, Austria. "For me, the best approaches are experiment and storytelling," she writes. "Never underestimate the power of a good, simple and enthusiastic story and its effect on students' interest in physics."

Jack Davies Hare, who currently works as a postdoctoral researcher at the Max Planck Institute of Plasma Physics in Garching, Germany, summarizes the challenges of "surviving the maelstrom inside ITER" in a striking manner. He too begins with a question: "How do you build something that can survive for twenty years in the harshest conditions ever created on Earth, with no chance of replacement or repair, and with no test facility to replicate this environment?"

Like Patricia and Jack, the contributors to this "fusion writers edition" of Fusion in Europe share a common passion to communicate not only their enthusiasm but also their awe at what they uncover when exploring the bewildering world of fusion.

In November, record neutral beam power of 30.8 MW were injected into a plasma on the JET tokamak at the Culham Centre for Fusion Energy (CCFE).

The new record was achieved during tests preparing the plasma scenarios required for JET's deuterium-tritium experiments in 2020, which aim to achieve high fusion power for a stable five seconds. Increased heating powers are crucial to achieving this target.

Beams of neutral particles (known as neutral beam injection) are one of the main plasma heating schemes on fusion machines such as JET and ITER. As well as supplying most of the heating power, the injection of energetic particles also provides useful diagnostic data for physicists.

CCFE's engineering team, which operates JET on behalf of European scientists under the EUROfusion consortium, has upgraded the neutral beam system from its previous capacity of 23 MW to a potential maximum of 34 MW. The extra power will support researchers using JET to simulate plasmas for the ITER Tokamak.

"The world's great powers can't agree on small steps to tackle climate change, but they're cooperating on a huge leap of faith in Provence." So begins a recent article in Bloomberg on the ITER fusion project. Describing ITER both as one of the world's biggest scientific puzzles as well as a trade puzzle, author Jonathan Tirone explains how a 35-country network is sharing intellectual property, collaborating to bypass difficulties, and ultimately—if ITER succeeds—providing a template for world powers to develop fusion reactors or their own.

Next month, ITER Director-General Bernard Bigot will be presiding over a major public event in Marseille: L'Usine Extraordinaire (Extraordinary Factories). The three-day exhibition, organized from 14 to 16 November 2019, brings together more than 50 industrial actors and aims to change the public's perception of "big industry" by highlighting technological innovation, excellence, discovery, and ... the possibility of exciting careers.

In a few decades, when dozen of fusion plants operate throughout the world and the first signs of alien life are detected in a faraway system, one will realize that it all started here, in a small corner of southern France, amidst the rolling hills of Haute-Provence.

The ITER site and the Observatoire de Haute-Provence are only 45 kilometres distant.

In 1995, two Swiss astronomers, Michel Mayor and Didier Queloz, coupled a highly sophisticated spectroscope to the Observatory's old 1.93-metre telescope (it was installed in 1958!) and discovered the first exoplanet—a "hot Jupiter" body orbiting the sun-like star 51 Pegasi, 42 light years distant from the Earth.

Last week, both Mayor and Queloz (along with astrophysicist James Peebles) were awarded the Nobel Prize in Physics for "forever changing our conceptions of the world."

By the time the first ITER buildings were coming out of the ground, close to 1,000 exoplanets had been detected. As of today, their number exceeds 4,500. Some of these worlds, made of solid rock like Earth, are orbiting the "habitable zone" of their star, where temperature allows water to be liquid and where life, whatever its form, is a possibility.

At an interval of a few years, on the ITER site and at the Observatoire de Haute-Provence, the seeds were sown for two momentous, game-changing pursuits: the harnessing of fusion energy and the quest for life outside our solar system.

In order to generate large amounts of fusion power, there needs to be a combination of two heavy hydrogen nuclei such as deuterium and tritium. But because of the radioactive nature of tritium—and also its scarcity—most experimental plasmas consist of deuterium only.

Although scientists are able to scale up the predicted performance of deuterium-tritium (DT) plasmas, there is nothing like using the real DT mix itself.

Next year, the European tokamak JET will be re-introducing tritium into its vacuum vessel for the first time since 1997.

The importance of its DT experimental campaign cannot be overstated for ITER. Until ITER starts operation with tritium in 2035, JET tritium and deuterium-tritium experiments will offer fusion scientists the opportunity to investigate physics relevant to high-fusion-power DT plasmas.

Roundtable, from TRT World, describes itself as a discussion program with an edge. Broadcast out of London, it's about "bringing people to the table, listening to every opinion, and analyzing every point of view." In September 2019, host David Foster invited an illustrious panel to discuss the potential of hydrogen fusion: ITER Director-General Bernard Bigot; Steven Cowley, director of the Princeton Plasma Physics Laboratory and former CEO of the UK Atomic Energy Authority; Mark Wenman, Imperial College London; and Colin Walters, current director of the UK Atomic Energy Authority.

Magyarósi Csaba, a popular Hungarian video blogger, has created a fast-paced and jaunty feature on ITER.

Travelling between experts at the Wigner Research Centre for Physics in Budapest and Hungarian staff at ITER, he introduces his followers to the principles of fusion before diving into ITER, literally, as his camera follows him in and out of buildings under construction, stairwells, offices, eateries, and even the equipment room for worksite visitors. 

His program, posted to YouTube on 13 September, has passed 190K views in the first two months.

In September, the US House Science Committee invited the ITER Organization to hold a mini "ITER Business Forum" in its chambers in Washington D.C. to inform US companies about upcoming business opportunities at ITER. Approximately 90 businesses attended the event, which was opened by ITER Director-General Bernard Bigot. The next round of planned tender offers was described, and Skype links were made available for direct question and answer sessions with managers and department heads on site at ITER.

See this page on the ITER website for more on current and forthcoming tender offers. 

From 26 to 27 August, representatives of Euratom and Rosatom met in Russia to discuss collaboration in the field of controlled nuclear fusion.

Representatives of the Kurchatov Institute, Rosatom, and ITER Russia hosted colleagues from EUROfusion, the Karlsruhe University of Technology (KIT) and the Belgian nuclear research centre SCK•CEN to discuss the possibility of joint tokamak experiments and collaboration in the areas of diagnostics, plasma-wall interaction, fusion neutron sources, and materials.

Collaboration and cooperation between the two institutions is made possible by the "Agreement between the Government of the Russian Federation and the European Atomic Energy Community (Euratom) in the field of controlled thermonuclear fusion" that was signed in 2001. Its stated purpose is "to "maintain and intensify cooperation in the areas of nuclear fusion energy on the basis of equality and mutual benefit in order to develop, particularly in the framework of activities connected with ITER project implementation, the scientific understanding and technological capability underlying a fusion power system.

At the Kurchatov Institute, visits were organized to the T-10 tokamak, as well as to T-15MD—an upgrade of the T-15 machine that is scheduled for completion next year.

In August, while on official visit to France at the invitation of President Emmanuel Macron, Prime Minister Narendra Modi of India shared his vision of cooperation in the field of energy on several occasions. At the UNESCO headquarters in Paris, he took pride in his country's participation in "the only fusion project under construction in the world." ''When fusion technology becomes available [...]," he said to expatriates gathered for the occasion, "this achievement will bear the mark of your contribution."

The full speech in Hindi is available on YouTube.

We regret to announce the passing, in August, of lifelong fusion advocate Romano Toschi.

Romano Toschi was a leading figure in the development the Italian magnetic confinement fusion program and played an important role in bringing the EU at the forefront of fusion research. He was known for his strong leadership and advocacy in furthering fusion and was a prime mover in the technical and political discussions leading to the establishment of ITER.

Below is an article describing his many contributions. EUROfusion has also published a tribute here.

"There's quite a significant crossover in the technologies between fusion and space. Both sectors have the need for components to be able to withstand high temperature, corrosion and be radiation-resistant. Equally, there is the requirement to use remote handling and advanced robotics in hazardous environments."

Heather Lewtas is the Programme Manager for Joining and Advanced Manufacturing at the Culham Centre for Fusion Energy (CCFE). At this year's Made for Space conference in the UK, she gave a talk on "Pushing the limits of component performance in nuclear fusion and space."

"I wanted to focus on the technology people working in fusion have really mastered, and how this can be transported to the space industry. Equally, what are the problems we have that the space industry could help us solve?"
