A key technology issue in magnetic fusion energy is plasma-materials interactions (PMI). Because our understanding of how materials change when exposed to burning plasmas over extended periods is limited, Oak Ridge National Laboratory (ORNL) has proposed a linear plasma simulator, the Material-Plasma Exposure eXperiment (MPEX), to test various fusion-relevant materials. Since this facility will expose various materials to conditions similar to those in a burning plasma (except for fusion-relevant neutrons) at steady state, effectively cooling the target plate which will be exposed to steady-state heat fluxes of several MW/m2 is a major challenge. The objective of this Master’s thesis is to use numerical simulation to evaluate and improve the thermal-hydraulic performance of a helium-cooled divertor design adapted for cooling the target plate in a linear plasma simulator.
