The emission properties of a plasma cathode based on a nanosecond pulsed glow discharge with currents of up to 200 A at a pressure of 5 × 10[sup -2] Pa are studied experimentally. Stable ignition and burning of the discharge are ensured if the current in the auxiliary pulsed discharge is 25-30% of that in the main discharge and its pulse duration exceeds that of the main discharge by more than an order of magnitude. Emission current pulses from the cathode with amplitudes of up to 140 A fully reproduce the discharge current and are determined by the transparency of the grid anode. [ABSTRACT FROM AUTHOR] |
