Voltage and Current Measurements of a Laser Preionization Triggered High Voltage Switch

reportActive / Technical Report | Accession Number: ADA638714 | Open PDF

Abstract:

Voltage and current measurements of a laser preionization triggered spark gap switch 50 kV, 18 kA, 100 nsec reveal a voltage drop across the gap of several kilovolts during the current plateau for a variety of gas mixtures. This voltage drop is much larger than what is generally believed to exist in a spark gap switch during the conduction phase. The reasons for the large voltage drop are explained,
