Effect of Transient Layers on Plasma Energy Transfer to Different Surfaces Under Qspa Exposures

Abstract

The plasma energy transfer to plasma-facing materials, as well as the energy and particles exhaust, needs to be extensively studied for the implementation of the next-step fusion reactor project. Analysis of plasma-surface interaction features has been performed using QSPA exposures of reference plasma-facing materials. The parameters of the plasma streams imitated conditions of transient events in a fusion reactor. The influence of an external magnetic field on the energy balance during the plasma-surface interaction is also discussed.
