Note: Compact, reusable inductive-storage-cum-opening-switch based 1.5 GW single-shot pulsed power generator

The results of a very-compact (Marx generator-cum-inductor confined into 0.20 m cylindrical diameter and 0.75 m length) and light-weight (<15 kg) pulsed-power generator are being presented in the paper. The load voltage at 10.5 Ω is measured 125 kV (150 ns full width at half maximum FWHM) with 1.5 GW peak-power. The use of single-optimized-exploding-copper-wire along with the use of air for all the switches of the generator (closing switches of Marx generator used as primary energy source and opening switch of exploding wire) make device very attractive. Marx generator shape itself provides the desired inductance for the inductive storage.
