Matereial erosion and erosion products in disruption simulation experiments at the MK-200 UG facility

摘要

Plasma/material interaction was studied in disruption simulation experiments at the plasma gun facility MK-200 UG. Graphite, tungsten and aluminium targets (beryllium-like material) were irradiated by intense plasma streams Under heat fluxes typical for international thermonuclear experimental reactor (ITER) hard disruption. Materials were Also exposed to radiation emitted by target plasma shields. Surface damage and erosion products were analysed.
