摘要: The operation of a planar diode with large area (64 cm2) ferroelectric plasma cathode based on BaTiO3 ceramics is studied. Diode parameters and the generated electron beam are investigated under accelerating voltage 200–350 kV pulse duration 250 ns. Parameters plasma, which forms surface due to incomplete discharge, reported as well. It shown that application this allows one produce an simultaneously pulse. generation current density up 20 A/cm2 divergence less than 1° demonstrated. governed by fills anode–cathode gap prior By proper adjustment almost constant impedance achieved. Measurements potential distribution in ...
