Performance of the Kirkcudbright capacitor bank system modifications for ETC operations

Summary form only given, as follows. The 29-module, 32 MJ capacitor bank at the Defence Evaluation and Research Agency Electromagnetic Launch Facility, in Kirkcudbright, Scotland, has been modified to enhance its capabilities in driving Electro Thermal (ET) and Electro Thermal Chemical (ETC) gun loads. The primary changes are: installation of equipment allowing capacitor banks to be connected in series pairs, for higher-voltage operation.; removable inserts for the module pulse-shaping inductors to reduce inductance by approximately a factor of two for some of the modules; and a set of high-energy inductors and associated buswork to allow insertion of a range of additional inductances in some modules The modifications allow a wide range of pulse shapes and durations to be delivered to ETC gun loads. The paper reviews the designs for the modifications to the bank, and describes the performance of the system.
