Abstract

This article describes the way to simulate interaction of a highly intensive plasma flux (of the type common in plasma focus devices) with materials. We apply 1D model of a target, assume a simple screening model of the plate by evaporated material. Moving, rigid computational mesh and enthalpy picture applied allow convenient and precise description of phase transitions in the sample. Intensive plasma bombardment causes destruction of the sample surface by melting and evaporation. The stronger the flux, the more heat is used to evaporate the sample and less is absorbed. The code purpose is to help extrapolate experimental plasma focus results to thermonuclear fusion devices.
