Calculation of one-dimensional plasma flows with allowance for the kinetics of ion collisions

The influence of kinetic effects on the generation of line X radiation during the spherical implosion of a laser corona plasma with two ion species is studied under the conditions prevailing in experiments with thin-wall spherical targets in the Iskra-5 laser facility of the All-Russia Research Institute of Experimental Physics (Sarov, Russia). Kinetic processes occurring in a multicharged plasma are investigated using a specially devised code for solving one-dimensional Landau equations for a nondegenerate multicomponent plasma by the Monte Carlo method (the KIN-MC code). The code was developed using the quasineutral plasma approximation under the assumption that the electron distribution function is locally equilibrium. The model equations are presented, the scheme of numerical solution is described, and the calculated results are discussed.
