Fast energy output from a high-current pulsed capacitor by using a pseudospark gap

Results of works on a fast energy output from a capacitor by using a pseudospark gap are described. For this purpose, an HCEIcap 50-0.1 capacitor was specially designed with a combined paper-film insulation impregnated with a castor oil with three types of films: mylar, polypropylene, and teflon. A TDI1-50K/50 pseudospark gap was modified so that the total circuit inductance did not exceed 10 nH. During tests at 40–45 kV, current pulses of ～100 kA with a 2.4 × 10¹²-A/s rise rate were obtained.
