A New Broadband Pulsed High Voltage Monitor

Abstract

Experimental results of a new GHz-bandwidth diagnostic for measuring pulsed high voltage are presented. The probe is a small helical coil that self-magnetically insulates to prevent turn-to-tum flashover. A small external B-dot sensor measures I-dot, the time rate of change of current in the probe. The voltage to be measured is equal to L* I-dot. This paper describes the experimental apparatus used to measure a 1 MV, 60 ns pulse with a rise time of 1.5 ns generated by LLNL's 2MV accelerator. Excellent agreement is obtained when comparing the output of the new probe with a conventional resistive divider technique. The major difference in the temporal shape of the waveforms was determined to be caused by the bandwidth limitation of the resistive divider probe.
