Breakdown in Vacuum by a Microwave Field Superposed with d.c. Voltage

The microwave breakdown and its suppression by superposing d.c. voltage was investigated at the frequency of 2.45 GHz with regard to the high power microwave techniques for heating fusion plasmas. An increase of about 60% in r.f. breakdown voltage was realized by superposing d.c. voltage of 1000 vol...

Zusammenfassung:The microwave breakdown and its suppression by superposing d.c. voltage was investigated at the frequency of 2.45 GHz with regard to the high power microwave techniques for heating fusion plasmas. An increase of about 60% in r.f. breakdown voltage was realized by superposing d.c. voltage of 1000 volts in the cavity, whose height was 2 cm, at the pressure of 1×10 -4 Torr.
