Wendelstein 7-X broke yesterday its own record with the 100 s discharge duration and ca. 400 MJ total energy injected into plasma.

This infrared image shows almost no thermal loads to the first wall, i.e. plasma is well insulated from the surroundings, which is essential for a future reactor. We call such state of plasma - detachment. It allows for longer operation of the reactor.

With 100 s plasma duration this is probably a world record for the duration of the detachment. (C) IPP

We plan to reach 200 seconds by the end of this campaign with 1 GJ injected into the plasma.
