摘要

The initiation of arc on a newly developed cathode has been investigated experimentally as a function of the pulse voltage and the repetition time of the pulse. It is found that glow current is expressed as i=I0eαt before arc is initiated, where I0 depends on the voltage and the repetition time, and α depends on the voltage but is nearly constant in the range of repetition time from 10 ms to 70 ms. The time lag at which arc occurs becomes shorter as the pulse voltage increases or as the repetition time decreases.Two methods for prompting the occurrence of arc discharges are also reported. One is to apply a prepulse of a weak discharge before each main pulse. The other is to apply the same voltage with the main pulse to a metal ring outside the glass envelope of discharge lamp.The former is more effective than the latter. Sometimes, no time lag of glow-to-arc transition was observed by the prepulse method, whereas the effect of the extenal ring is only to reduce the time lag to a half.
