Simulation of Plasma Induced Material Damage with H-Ion Beams
Plasma wall interaction is a designation for several sub-processes affecting the surface of the plasma-facing components in a thermonuclear fusion reactor. Here besides electromagnetic radiation, arcing, and neutron irradiation, two processes may play a life-limiting role for the so-called first wall; namely, thermal fatigue due to the pulsed operation of a Tokamak and thermal shock loading by plasma disruptions or run-away electrons during unstable plasma states.
