Abstract

Summary form only given. A compact low-inductance capillary discharge system designed for the study of a capillary plasma is described. The system is able to produce a plasma Z-pinch in a gas by the switching of a 30 nF capacitor bank into a gas loaded in a 21 cm long alumina capillary at a voltage up to 80 kV. The capillary current pulse is measured by a Rogowski coil and at 40 kV charging voltage its maximum is 10 kA, the pulse width is 170 ns and rise time is 60 ns. The system is intended to be optimized further to obtain a Ar⁸⁺ laser.
