EROSION AND DEPOSITION OF WALL AND LIMITER MATERIAL IN JET
Study of walls and limiters of plasma machines by means of surface analysis techniques provides valuable information for the understanding of the causes of impurity fluxes into the plasma which is one of the most important problems of today's fusion research. Therefore, surface analyses of JET graphite limiters have been performed after the experimental periods in 1983 as well as in 1984. In addition graphite and metal long term samples (LTS) have been analyzed. They were uniformly distributed over the vessel wall and placed well in the shadow of the bellow shields. They have been exposed to all 1984 discharges, in order to monitor effective erosion and redeposition of wall material in an extended run of the machine.
