A fast electrical discharge, created in an initially evacuated polyacetal capillary, has been simulated and realized. Steady state discharge parameters for polyethylene and polyacetal have been compared on the basis of the IONMIX code results. Space-time dependencies of plasma electron temperatures and densities under various experimental conditions have been judged on the basis of one-dimensional MHD model. Measured and evaluated macroscopic parameters correspond to each other.
