Abstract

This paper attempts to discuss the pseudo-spark which is developed for high voltage and high current. The pseudo-spark switch is on the basic of the Paschen's law. The pseudo-spark switch fabricates the glass chamber. The pseudo-spark switch consists of hollow cathode, hollow anode, and trigger. The pseudo-spark switch is operated at the voltage of 20 kV and the pressure range of $20{\sim}80$ mtorr with He-gas. The switching current of the pseudo-spark switch was measured as 65 kA, and the duration of the pulse was about 100 ${\mu}s$. This paper describes the results of tests and the characteristics of the switch.
