Enhanced Free Dielectric Recovery for Kilohertz Operation of Spark Gaps
Abstract
High power radiofrequency (HPRF) systems with high pulse repetition rate (PRR) capability have operational advantages by putting more energy on target even with moving platforms. Modulators using Tesla transformer-based high voltage multiplication schemes are of interest because of their compact size and the potential of using folded energy lines for even further reductions in size and weight. The potential, however, is not yet fully realized because of limitations on the PRR from switch the secondary side. Attempts to increase the capability used gas flow with modest success but at the cost of increased size and weight. The PRR for sealed volumes canbe increased with improvements in the gaseous insulator#s voltage recovery time # the time for the spark gap to again hold off the full switching voltage. Physical parameters such gas type and pressure as well as physics-based techniques for plasma channel neutralization will be evaluated for high power operation at 1kHz pulse repetitionrate.
