JET, the Joint European Torus in Culham, Oxfordshire (UK), has just kicked off a third and final campaign in deuterium and tritium. The planned experiments, known as "DTE3," will run for seven weeks and focus on plasma science, materials science, and neutronics.

This campaign comes just 20 months after JET demonstrated sustained fusion over five seconds at high power and set a world record. In June, JET celebrated 40 years of science.

JET's research findings have been critical to planning at ITER, as well as to that of the UK's prototype fusion powerplant STEP, the European DEMO prototype fusion plant, and other national laboratory and private projects around the world.  

Repurposing and decomissioning activities on JET are scheduled to begin in 2024. 

See the announcement on the UKAEA/Culham Centre for Fusion Energy website.

For the third year in a row, the Department of Physics at the Technical University of Denmark (DTU) has held its Fusion Energy Summer Camp for high school students.

19 participants aged 16 to 19 got to work as researchers and conduct experiments on DTU's small, and Scandinavia's only, NORTH tokamak. From early morning to late evening, from 30 July to 4 August, they followed lectures, practiced problem solving and programming in fusion energy and plasma physics, and participated in experiments, while also having fun and getting a taste of university life on campus.

The DTU Physics teams thanks the Novo Nordisk Foundation for its generous support in helping to inspire the young generation to consider an education in science and engineering and be part of the push to develop a sustainable future.

The transition to superconducting has been observed in the JT-60SA's central solenoid and toroidal field magnets, according to reporting by the team.

Superconductivity is a natural property of certain metals, alloys and ceramics when cooled below a defined "critical temperature." Below the critical temperature—which varies for each material—electrical resistance drops to zero, allowing these materials to carry large amounts of electrical current without losing energy.

JT-60SA's central solenoid is wound from niobium tin (Nb3Sn) cable-in-conduit conductor, which in the absence of any magnetic field becomes superconducting at about 18 K (-255°C). Early on 22 July the four modules of the central solenoid reached this temperature and the resistance of the magnets dropped to almost zero. The superconducting transition for the tokamak's 18 toroidal field coils and 6 equilibrium field coils (made from niobium titanium (NbTi) cable-in-conduit conductor) occurred at about 9 K (-264°C) on 24 July.

The JT-60SA tokamak is a joint program of fusion research and development agreed and co-financed by the European Atomic Energy Community (Euratom) and the government of Japan.

The sixth and last episode of Season 2 of The ITER World is now available.

"Narrating A Giant" caps off the season by interviewing ITER Head of Communication Laban Coblentz. What public information strategy should be followed for this project that has so many complex layers of science, engineering, technology and politics? How to sustain interest in a project that spans decades? How to combat misconceptions?
