Abstract :
An analysis of a numerical simulation of the electron beam drive in Z-pinch discharges are represented in the paper. The results of the plasma inhomogeneity effect along the Z-axis on the plasma column resistance are given. The electron beam is generated as a result of the electron run-away mechanism at the places of the strongly-compressed plasma production in the vicinity to the pinch axis. The main electron beam fraction is generated at the stage of plasma column expansion
