A theoretical physicist, but one who views theory as something "to be put to use," Alain Bécoulet can speak (and write) about fusion in terms that are both simple and inspiring. In his recently published Star Power: ºÚÁÏרÇø and the International Quest for Fusion Energy (MIT Press), he offers a concise and accessible overview of fusion energy promises and challenges, not only explaining the underlying science and technology but also describing the massive international effort to harness this potential new energy source.

Having embraced plasma physics in the mid-1980s as a student at France's prestigious École Normale Supérieure, Bécoulet draws from his long experience in fusion research, first at France's Institute for Magnetic Fusion Research (IRFM), and since February 2020 as head of the ºÚÁÏרÇø Engineering Domain, to explain how the long-pursued dream of harnessing the energy of the Sun and stars is on the verge of becoming reality.

In this ºÚÁÏרÇø Talk, the seventh in the series, ºÚÁÏרÇø scientific expert Joseph Snipes walks us through plans for ºÚÁÏרÇø operation. What does the "Q" in ºÚÁÏרÇø's goal of Q=10 stand for? How will the machine and its systems be prepped for operation? What are the different steps between First Plasma and full fusion power operation?

The ºÚÁÏרÇø Research Plan will proceed in four stages—a careful step-by-step strategy designed to achieve high plasma performance operation up to a plasma current of 15 MA, with key milestones along the way. Learn about the staggered assembly of key systems, the specific goals of each operation phase, the means to achieve the goals, and the importance of robust plasma control. By the end of the talk, you'll know (a lot) more about the unique capabilities of the ºÚÁÏרÇø experimental device.

Alberto Loarte, head of the Science Division at the ºÚÁÏרÇø, introduces us to the physics of ºÚÁÏרÇø plasmas and explains how the physics justifies the design of the machine. He reviews the deuterium-tritium nuclear fusion process, the role of magnetic fields in fusion, the specificities of the tokamak configuration, energy and particle confinement, heating and fuelling, and finally fusion power, particle exhaust and plasma-wall interactions. And he does it all in a clear and understandable way!

There are presently two approaches to realizing hydrogen fusion. One, implemented in tokamaks and stellarators, consists in heating a very tenuous plasma to temperatures in the 100 million degrees Celsius range and to confine it in a magnetic cage—this is magnetic fusion. Another, called inertial fusion, is implemented in installations such as the American National Ignition Facility (NIF) or the French Laser Mégajoule. In inertial fusion an array of hundreds of powerful lasers, precisely focused, is used to compress to extreme density (and hence very high temperature) tiny hydrogen-filled capsules inside which fusion reactions can occur.

Now, a third approach is being considered and experimented at , in Cleveland, Ohio. Called "lattice confinement fusion," it could one day provide enough power to operate small space probes or rovers for planetary exploration.

In lattice confinement fusion (LCF), a beam of gamma rays is directed at a sample of erbium or titanium saturated with deuterium nuclei (deuteron). Occasionally, gamma rays of sufficient energy will break apart a deuteron in the metal lattice into its constituent proton and neutron. The energetic neutron has a chance of colliding with another deuteron in the lattice, imparting it with some of its energy. And sometimes that energy is enough for deuterons to fuse into a helium-3 nucleus (helion) and give off useful energy. A leftover neutron could provide the push for another energetic deuteron elsewhere in the lattice.

"Our work represents just the first step toward realizing that goal," say the scientists involved in this endeavour. "If the reaction rates can be significantly boosted, LCF may open an entirely new door for generating clean nuclear energy, both for space missions and for the many people who could use it here on Earth."

During the operation of a fusion machine, it is important to know the surface composition of the plasma-facing components, which can evolve over time (erosion, oxidation...) and modify plasma interaction conditions.

The team at the WEST tokamak in France is testing a new kind of diagnostic, called the fibered LIBS (for Laser-Induced Breakdown Spectroscopy), to characterize internal surfaces of WEST and later ºÚÁÏרÇø. 

In LIBS, a high-intensity pulsed laser beam is focused on the surface to be analyzed. The laser/matter interaction leads to the ablation of the material and the creation of a plasma plume. The spectral analysis of the plasma emission gives access to the elemental composition of the ablated material and thus the composition of the material under study.

Installed on an inspection robot equipped with an articulated arm, the LIBS tool consists of an optical fibre carrying the incident laser light and the light emitted during the interaction of the laser beam with the material under study. The diagnostic can not only characterize all internal surfaces of the machine and follow their evolution, but also (in ºÚÁÏרÇø) monitor tritium concentration in the first wall and detect eventual helium bubbles in plasma-facing components coming from the interaction of fusion neutrons with the materials.

The first tests were carried out in December 2021. Read the original article in or in .

For 15 years ºÚÁÏרÇø has been opening its doors to visitors, either in small groups or during regular Open Doors Days. Approximately 160,000 visitors from all horizons—school children, students, members of the public, companies, politicians—have passed through the ºÚÁÏרÇø gates since 2007, returning home with a better idea of the scale and importance of ºÚÁÏרÇø and of the passion that animates the men and women who work here.

Because in-person Open Door Days have been impossible for the past two years, the ºÚÁÏרÇø Communication team innovated in 2021, creating a virtual experience on line for "visitors" from around the world.

Demonstrations, livestreams from the worksite, videos, presentations, virtual reality ... there is something for everyone.

The three-hour event is now available in replay. Follow to view it.

The 11th ºÚÁÏרÇø International School will be held from 25 to 29 July 2022, hosted in person by the U.S. Burning Plasma Organization, University of California at San Diego, and General Atomics.

The subject of this year's school is "ºÚÁÏרÇø Plasma Scenarios and Control." As the start of ºÚÁÏרÇø operation approaches, it is timely to address this challenging multidisciplinary topic: the development of integrated operating scenarios and required plasma control to facilitate the ºÚÁÏרÇø goals, particularly for plasmas self-heated by fusion-born alpha particles.

The ºÚÁÏרÇø International School is organized regularly with the goal of giving young scientists and engineers a taste of the stimulating, multi-disciplinary and challenging field that is nuclear fusion.

In a rare and memorable moment, the Joint European Torus (JET) team today received His Royal Highness the Prince of Wales for a tour and first-hand discussion of fusion energy. Long known as an advocate of environmental awareness and sustainable energy, Prince Charles was, according to UKAEA CEO Ian Chapman, "keen to understand more about how fusion can be a critical piece of the future global energy puzzle." Together with European and UK officials, ºÚÁÏרÇø Chief Scientist Tim Luce was present to meet the Prince of Wales and explain the JET-ºÚÁÏרÇø connection.

Currently the world's most powerful tokamak, JET is a direct precursor to ºÚÁÏרÇø, and recently celebrated the completion of its 100,000th pulse. New scientific results from the most recent JET deuterium-tritium campaign will be released in February.

During his visit, the Prince of Wales was introduced to ºÚÁÏרÇø by Tim Luce, head of the ºÚÁÏרÇø Science & Operations Domain (left).

Since its inauguration in 1983 in the presence of Her Majesty Queen Elizabeth II, the European tokamak JET has cemented its reputation as "one of the most important machines in the history of fusion energy research," according to Ian Chapman, CEO of the UK Atomic Energy Authority. On 18 January 2022, the machine ran its 100,000th plasma pulse.

JET, for Joint European Torus, is the focal point of the European fusion research program, designed to study fusion in conditions approaching those needed for a power plant. It is the only experiment that can operate with the deuterium-tritium fuel mix that will be used for commercial fusion power (and in ºÚÁÏרÇø).

In 1997 JET successfully produced a world record 22.5 megajoules of fusion energy and 16 megawatts of fusion power during the first dedicated deuterium-tritium experiments, proving large amounts of power can be produced from fusion.

In 2011 JET was equipped with a new ºÚÁÏרÇø-like inner wall made of beryllium and tungsten metals, enabling scientists to develop plasma scenarios that resemble as closely as possible those planned for ºÚÁÏרÇø, investigate the interaction of the plasma with wall materials, and study the accumulation of tungsten from the wall in the plasma core.

In 2021, JET carried out a second full-power run of experiments using deuterium and tritium. Stay tuned: the results from these experiments will be announced in early February 2022.

The JET facilities located at the Culham Centre for Fusion Energy () in Abingdon, Oxfordshire UK, are collectively used by all European fusion laboratories under the . ºÚÁÏרÇø 350 scientists from EU countries (plus Switzerland, the UK and Ukraine), and more from around the globe, participate in JET experiments each year. CCFE is responsible for operating the facility for fusion researchers and for maintaining and upgrading it. This work is carried out under a contract between the European Commission and the UK Atomic Energy Authority (CCFE's operator). 

The ºÚÁÏרÇø community congratulates the JET team on its 100,000th pulse!
