Title: Low-jitter, high-voltage, infrared, laser-triggered, vacuum switch

Abstract

A laser-triggered, high-voltage vacuum switch using a triggering pellet embedded in the cathode has been developed. The switch was constructed with tungsten electrodes and used either KC1 or Poco graphite pellets. An aperture in the anode allowed the laser beam to strike the pellet on the cathode surface. Reliable triggering was achieved with only 200 {mu}J of laser energy at a wavelength of 1064 nm. The switch was operated with an A-K gap voltage ranging from 5- to 30-kV with switching currents up to 15 kA peak. The delay time of the switch vaired from 70 {plus minus} 3 ns at 25 kv to 500 {plus minus} 100 ns at 5 kV. 6 refs., 6 figs., 2 tabs.
