Investigations of Pulsed Vacuum Gap.

Abstract

Past research and the current status of understanding of electrical breakdown of vacuum is reviewed. This review includes DC, AC and pulsed vacuum gap breakdown. Measurements have been performed to determine the role of microparticles in pulsed vacuum gap breakdown. These measurements consisted of directly measuring the charge and velocity of microparticles produced using pulsed excitations up to 100kV. Measurements show that microparticles are present prior to, during, and after vacuum breakdown. Typical microparticle charge and velocity values for 100kV/cm fields are 10 to the minus 13th power and 75m/s. Keywords: Vacuum breakdown, Microparticles, Pulsed breakdown, Charge detection, and Vacuum prebreakdown mechanisms.
