High Voltage Generator With Adjustable Delay Between Two Nanosecond Pulses

In this letter, we present the experimental setup of a newly designed, high voltage (up to 10 kV), nanosecond duration pulse generator. Based on the frozen wave concept, the generator includes two optoelectronic photoconductive switches placed in a compact three ports coaxial structure. The generator is able to produce unipolar, bipolar and paired pulses with adjustable inter-pulse delay between 5 ns and 200 ns. An electromagnetic frequency characterization of the generator evidenced its suitability for the implementation of kilovolt ultra-short pulse with delay tunability.
