“…High-power glow discharges have been used for electron beam welding (Dugdale 1971, Isaacs 1967, in neutron tubes (Braddock et al 1961), and in lasers (Crocker et al 1972). Such applications make use of the fast electrons bombarding the anode, and the neutrals and ions bombarding the cathode in low-pressure, high-voltage glows.…”

A method of stabilizing low-pressure, high-power (100 kW) glow discharges against glow-arc transitions is described. An external circuit consisting of an inductor, a series resistor and a shunt capacitor is used to cause rapid arc extinction and avoid arc reignition. Mean power levels of 100 kW and peak powers of 160 kW have been sustained throughout many successive glow-arc transitions, and powers of 10 kW have been sustained for several seconds using a suitable d.c. power supply. The method may be suitable for applications such as electron beam glow discharge welding, neutron tubes, gas lasers, X-ray tubes, high-power transmitter valves, and microwave klystrons.
