|Abstract:||The effect of the irradiating conditions by high-power pulsed ion beams (HPPIB) on the ablation rate was studied. The conditions of irradiation (ions of carbon and protons, ion energy E=300-600 keV, the ion current density in a pulse j=60-500 A cm" pulse duration т=50-100 ns) were realized in Temp and Vera accelerators. The study of the evaporation kinetics was carried out using targets manufactured from GS26NK nickel super-alloy with NiCrAlY coating and from VT9 and VT18U titanium alloys with ZrN and TiSiB coatings. It is shown that values of the ablation rate achieve 0.04 µm (TiSiB), 0.4 µm (NiCrAlY), and 1 µm (ZrN) during a pulse under the optimal conditions of HPPIB irradiation.|
