ÌÇÐÄÆƽâ°æ

From a UKAEA  on 20 December 2023.

Some 40 and a half years after its first pulse on 25 June 1983, JET delivered pulse number 105,842 on Tuesday 18 December 2023.

UKAEA Chief Executive Officer, Prof Sir Ian Chapman, who was in attendance in JET's control room for the final plasma experiment, said: "This is the final milestone in JET's 40-year history. Those decades of research using JET by dedicated teams of scientists and engineers have played a critical role in accelerating the development of fusion energy."

JET's final day of plasma continued to push scientific boundaries, firstly attempting an inverted plasma shape for the first time at Culham before deliberately aiming electrons at the inner wall to improve understanding of beam control and damage mechanisms. The findings of these experiments will support the development of ÌÇÐÄÆƽâ°æ.

JET will now move on to the next phase of its life cycle in early 2024 for repurposing and decommissioning, which will last until approximately 2040.

JET was operated at the Culham Centre for Fusion Energy as a Joint Undertaking of the European Community between 1977 and 2000, with the Euratom Research and Training program contributing approximately 80 percent of JET operation costs through 2021. Under the operation of the United Kingdom Atomic Energy Authority (UKAEA) since 2000, JET was used by 4,800  consortium experts, students and staff from across Europe.

On Thursday 14 December, join in for Episode #2 of the IAEA Fusion Energy Webinar Series. "Fusion Energy at COP28: A promising emerging climate solution" will address the growing momentum worldwide behind fusion as a climate solution, as evidenced most recently at the COP 28 climate summit in Dubai.

Adam Danilowicz, of the IAEA, will moderate a panel with distinguished guests:

Scott Hsu, Senior Advisor and Lead Fusion Coordinator Office of the Under Secretary for Science & Innovation, US Department of Energy

Tim Bestwick, Chief Development Officer and Deputy CEO, United Kingdom Atomic Energy Authority 

Stephanie Diem, Assistant Professor, Department of Engineering Physics at the University of Wisconsin-Madison

Andrew Holland, Chief Executive Officer of the Fusion Industry Association

On Tuesday 12 December, from 10:30 to 11:45 in the morning (GMT), the JET tokamak team will be hosting a special *LIVE* YouTube show direct from the JET control room. 

JET operation ends this week with final plasma shots planned on 14 and 15 December. Join the team to look back over 40 years of research on JET and look ahead toward the future of fusion. The agenda includes a talk on "What's made JET special"; a discussion about achievements at JET; an interview with Tony Donné from EUROfusion; and a discussion on the next steps in fusion.

Participants can ask their questions by chat during the live stream. See all information .

Have you written a fusion-related Master's thesis in 2023? Then you can participate in the FuseNet Master Thesis Prize 2023!

To stimulate excellence in fusion research, FuseNet would like to award several students for outstanding Master's theses that were carried out in Europe or in collaboration with international institutions.

Nominations for this Master's thesis prize can be made through the FuseNet website at the link below. Please make sure that the submission is agreed with your institution and its FuseNet contact person. Only one submission per FuseNet member institution is allowed. The submission deadline is 1 February 2024.

Félicie Albert, Director of the Jupiter Laser Facility at Lawrence Livermore National Laboratory () in California, delivered a guest lecture on 4 December 2023 to several hundred members of the ÌÇÐÄÆƽâ°æ community. She returned to the achievement of fusion ignition at the National Ignition Facility in December 2022—a first-of-class milestone that had reverberated around the world and that has been replicated several times since—and brought the audience up to date on future plans for the facility.

"The National Ignition Facility has not yet reached its full potential; we have many plans for the future," she said. Increasing the energy of the laser, achieving more routine implosions of the deuterium-tritium target, and sustaining the facility through the maintenance and replacement of components are all on the list. As for the longer-term prospects of designing and building a fusion power plant based on laser technology (inertial fusion), she described the many scientific and technological challenges that would have to be overcome.

Director Albert also took time to describe other laser facilities at the Lawrence Livermore National Laboratory where research activities are underway to investigate particle acceleration in laser-driven plasmas as a way to generate x-rays that have unique properties and that can be used for non-destructive examination of materials or the probing of matter in extreme conditions.

Félicie Albert is a Fellow of the American Physical Society (APS) and the recipient of numerous awards including the APS Katherine E. Weimer Award (2017) and the Presidential Early Career Award for Science and Engineers (2019).

After dedicating their careers to fusion power development, five recently retired engineers have launched an educational website, Facts About Fusion, that is designed to make the intricate world of fusion energy understandable and engaging for everyone.

Bill Spears, Federico Casci, Werner Gulden, Antonino Cardella, and Lorenzo Virgilio Boccaccini set out to give "a grounded view of the requirements, aims, and variety of fusion power development, highlighting the achievements so far, the current status, and the steps still needed to reach an acceptable solution."

What sets this site apart, according to its authors, is its objective viewpoint. "While the authors are knowledgeable and experienced in the field of fusion, their retirement status allows them to offer a neutral perspective that complements existing fusion project websites. This unique vantage point enhances the website's goal of fostering a better-informed public."
