Abstract

The four-frame high-speed camera has been used to study the evolution of the plasma sheath structure and dynamics in the visible spectral range for final stages of plasma-focus phenomena. In order to simulate the main features of the plasma sheath evolution, a two-dimensional, two fluids, and nonideal magnetohydrodynamics (MHD) code has been developed. The comparison between experimentally recorded plasma images and the results taken by MHD numerical modeling has been made.
