Abstract
The results of tests of a pulsed e-beam system for the diagnostics of rarefied gases via their e-beam-excited emission are presented. When u sed, a pulsed e-beam appreciably reduces the emission fraction due to secondary electrons and makes it possible to measure the gas density a nd the population of molecular energy levels at increased pressures (u p to 100 Pa for nitrogen) as well as to study nonsteady-state processe s in the excited gas with a 200-ns time resolution.
