Transport and Redeposition of Eroded Material in JET
Erosion and redeposition of eroded material was measured during the JET. Mark I carbon divertor operational period from April 1994 until March 1995 on the walls of the main chamber, the poloidal inner and outer wall limiters and the divertor plates by quantitative surface layer analysis. Ni + Cr + Fe is eroded predominantly from the inner wall vessel wall and Be from the outer vessel wall. Carbon is eroded from the plasma exposed limiter faces and the plasma exposed parts at the divertor strike points. The material eroded at these areas is predominantly redeposited at the limiter sides and the divertor in shadowed regions and the corner.
