Abstract

JET has operated initially with graphite limiters and Inconel walls. An inspection after twelve months of operation showed damage to the inner wall, mainly due to runaway electrons. About 1 kg of Inconel was melted. To inhibit this source of metal contamination of the plasma — metal droplets were deposited on the limiters — 20 m2 of graphite tiles were installed at the inner wall. They will also act as protection against beam shine-through as soon as neutral injection becomes available.
