Fast Capacitor Bank for Pulsed Magnetic-Field Studies

The design of a 20 kV, 60 , μF, 12-kJ capacitor bank for pulsed magnetic-field studies is reported in detail. In particular, a parallel-plate discharge circuit is described which results in a total bank inductance of 120 nH. Initial experiments with a flux concentrator magnet coil yielded a magnetic field of 250 kG in a volume of 2.41 cm3 at a bank voltage of 14 kV.
