Influence of thermophysical properties of the solid dependence from temperature on the thermal characteristics and erosion under the action of high-power pulsed ion beams

Abstract

This paper presents data on the evolution of erosion, melting, evaporation of matter under the influence of powerful pulsed beams of carbon ions. The calculations of dependence of physical characteristics on the temperature are performed. Considered current density 300-1000 A/cm2 at an initial energy of the beam particles equal to 300 kEv, and 70-140 A/cm2 for the initial energy of beam particles equal to 1 MeV. Correct cases of neglecting dependencies on temperature are established.
