As EUROfusion’s flagship device JET went into shutdown on November 15, 2016 JET researchers and engineers marked the 2015-2016 experimental campaign as one of the most successful in the long history of JET. The device was able to meet almost all of the goals set for the campaign.The campaign had three highlights: rehearsal of the procedures for future tritium-tritium and deuterium-tritium experiments, the hydrogen campaign during which physicists learned about the dependence of plasma parameters on the mass of the hydrogen fuel used, and the high-power deuterium campaign. And all these experiments achieved expected results.

This success means that JET is right on track for carrying out the tritium-tritium and deuterium-tritium experiments in upcoming campaigns – experiments that will be crucial foundations when ITER begins operations in the future to prove the feasibility of fusion energy.

With JET in shutdown now, EUROfusion has started with preparations for the next scientific programme. Researchers are going to analyse the results in detail, in order to prepare for the next experimental campaigns, and draw some conclusions for ITER operation. And, the focus will remain on the completion of the tritium-tritium operation in 2018 and the deuterium-tritium one in 2019-2020. The device is also going to get some sprucing up, starting with upgraded components of the NBI system and a new Shattered Pellet Injector technology, which will allow researchers to study disruption mitigation scenarios. So the shutdown looks likely to be as busy as the experimental sessions for researchers and engineers, but JET plasma operation will take a well-deserved break till it starts again next year.
