Abstract

Intense pulsed electron beams with remarkable parameters are generated in high voltage (5-30 kV) transient hollow cathode discharges (THCD). The most efficient THCD configurations for generating such electron beams are the pseudospark, the channel spark and preionization-controlled open-ended hollow-cathode (PCOHC) configurations. The beam parameters such as current, pulse length, and electron energy are measured for all three configurations using the same diagnostics. The dependence of the beam parameters on the discharge geometry, voltage, external capacitance and gas pressure is compared in all three configurations.
