Abstract

This paper presents the second phase of a research programme aimed at producing twin series of high-voltage pulses from the single discharge of a capacitor into multiple arrays of exploding metallic wires. Details of the design and construction of a generator that is able to produce either three 200 kV pulses, two 250 kV pulses or a single 500 kV pulse, on resistive loads between 50 and 100 Ω at each output, are given. In addition to describing the design of the exploding wire arrays, the paper also details other ancillary equipment that is needed for the generator. This includes the two compact air-cored transformers that provide the twin series of output pulses at the required voltage. The experimental performance of the generator is shown to be close to that predicted by numerical modelling.Results are presented with the resistive loads replaced by x-ray heads, and ways by which the system can be further developed to drive microwave sources are discussed.
