A solid state pulser for the hydrogen bubble (flow visualization) technique

Abstract

A compact solid-state unit which provides voltage pulses for the hydrogen bubble flow visualization technique is described. The unit provides voltage pulses in the range 05-50 ms in duration at rates which may be varied from 03-33 pulses s⁻¹. Voltage pulses up to 400 V dc may be used. A typical photographic record is presented.
