A single gap Pseudospark based hollow cathode plasma electron gun has been developed at CEERI. An experimental investigation for the above electron gun was conducted at different operating conditions in argon and hydrogen atmosphere. The electron beam (current ≥ 50 amps, density ≈ 700 Acm-2) is travelling more than 200 mm in the drift region through gaseous environment without using guiding magnetic...
Modes of precision triggering of a high-pressure nitrogen spark gap at voltages in the range from some tens of kilovolts up to one hundred of kilovolts have been investigated. The spark gap was triggered by a high-current electron beam. Experimentally, a total jitter no more than 25 ps relative to the leading edge of the beam-accelerating voltage pulse was attained. The time for which the spark gap...
Summary form only given. Breakdown of the gaps with a non-uniform electric field filled with nitrogen and air as well as with other gases under high- voltage nanosecond pulses was investigated. It is shown that conditions of obtaining a diffuse discharge without a source of additional ionization are extended at the voltage pulse duration decreasing. A volume discharge is formed due to the gap pre-...
