Generation of a microsecond electron beam in a plasma-filled diode

Results of experimental study of a plasma-filled diode are presented. The diode was filed by a plasma from plasma guns. Two different regimes were tested. In the first one the plasma cloud was localized at the anode region. In this case there were not found a stable low impedance mode of a diode operation. In the second regime the diode was filled by plasma completely before a high voltage pulse and an additional plasma cloud was also created in the drift region. In this regime a low impedance accelerating gap, stable
