Аннотация

The effects of powerful pulsed ion and high-temperature plasma fluxes generated in a plasma focus (PF) device and the effect of free running laser radiation on a corundum (α-Al2O3) ceramic produced by powder technology are studied. The power flux density q and acting pulse time τ for plasma stream, ion flux, and laser irradiation were qp ≈ 107 W/cm2 and τp ≈ 100 ns, qi ≈ 108 W/cm2 and τi ≈ 20 ns, and ql ≈ (3–5) × 105 W/cm2 and τl ≈ 0.7 ms, respectively. The resistance of the ceramic to pulsed energy fluxes was estimated by the weight loss of irradiated specimens and by the surface layer defects (damage). The combined use of PF and pulsed laser irradiation is shown to allow simulation of the extreme erosion and damage of materials in thermonuclear fusion facilities (such as ELM effects in ITER or at the first wall of inertial confinement chambers).
