Title: Performance of a 30-kV, 1-kHz, nanosecond source

Abstract

An existing pulser at LLNL was modified to increase its repetition rate to 1000 Hz. Spark gap recovery measurements were made for both the Marx and the Blumlein output switches. Recovery times of less than 1 ms were recorded without gas flow in the switch chambers. Low pressure synthetic air was used as the switch dielectric. Longer recovery times were necessary to over-voltage the switch. The output of the pulser was used to drive a log-periodic-dipole-array. Measurements were made on the transmitted pulses in an anechoic chamber and yielded a center frequency of 80 MHz. This paper describes the modifications made on the pulse generator, discusses the spark gap recovery data, and summarizes the performance of the pulser at 1 kHz. In addition, a brief description of the antenna is given along with the field measurements that were made in the EMPEROR facility.
