Abstract

By a gas discharge, a channel with low density plasma is formed, which in 10-100 /spl mu/sec transforms by cooling into a low density hot gas channel. The gas density was decreased by a few percent of the initial value. If then the second nanosecond voltage pulse is applied to the gap the electron beam of a short duration may be generated in this gas channel. The processes of spark formation and cooling in H/sub 2/ as well as the comparison with the experiment were studied by means of a computer simulation. Different aspects of nanosecond generators are considered in order to increase the efficiency of such electron beam generation.
