Abstract

A high-voltage pulse output modulator using a step-up transformer with two stages of magnetic pulse compression circuits has been developed as a spiker for the purpose of obtaining the breakdown of the gas mixture when using the spiker-sustainer excitation technique for pumping XeCl discharge lasers. When the transformer input is fed by a current pulse with a peak value and a full width of 1.16 kA and 1.6 μs, respectively, formed by a discharge of an initially charged 19-kV, 57-nF capacitance in series in the transformer primary loop, the 2.7-nF output capacitor bank (Cp) of the spiker can be charged up to 67 kV with a (10%-90%) rise time of 59 ns. The modulator has been tested at a repetition rate of up to 600 Hz in burst mode using a resistor in parallel with Cpas the load.
