Plasma maser with magnetic self-insulation; [Плазменный мазер с магнитной самоизоляцией] voltage of 550
kV. So short pulses determined the maser operation regime, namely, UWB noise amplification
Experimental study of a plasma maser based on accelerators with different voltage pulse duration with single pulses of a dome-shaped accelerating voltage with an amplitude of 270
kV, a base duration of 50 ns
