First measurements of the ion energy distribution at the divertor strike point during DIII-D disruptions

Abstract

Plasmdwall interaction studies are being carried aut using tht Divertor Materials Exposure System (DIMES) on Dma. The objective of the experiment is to determine the kinetic energy and flux of deuterium ions reaching the divertat target during argon-induced radiative disruptions. "he experimenr utilizes 8 special slotted ion analyzer mounted over a Si sample to collect the fast charge-exchange (CX)
