What’s New

The 2015-2016 experimental campaign at the JET tokamak, Europe's flagship device, came to an end on 15 November with nearly all goals met, according to a recent article published on the EUROfusion website.

Highlights included rehearsing the procedures for future tritium-tritium and deuterium-tritium experiments; running a 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. 

This success means that JET is right on track for the tritium-tritium and deuterium-tritium experiments planned for upcoming campaigns, which are expected to provide important results for the operation of ITER.

JET will restart operations in 2017.

After four years of non-stop work, the French tokamak Tore Supra has now become WEST,the tungsten (W) Environment Steady-state Tokamak. Equipped with an actively cooled tungsten divertor and additional power, experiments at WEST will provide precious data on operation in a tungsten environment in advance of ITER operation.

Considerable modification to the machine's internal elements has been carried out. New components have all been installed in the vacuum vessel (divertor coil windings, protection panels, antennas, diagnostics, tungsten plasma-facing components) and the chamber has now been closed for final commissioning before plasma operation.

The transformation mobilized more than one hundred people: staff from the Institute for Magnetic Fusion Research (CEA-IRFM) and also WEST partners, in particular Chinese and Indian on-site collaborators.

Following the upcoming divertor coil impregnation and integrated commissioning, WEST will embark on its scientific life focused on the preparation of ITER divertor operation.
