Initiation of an Arc Discharge in a Coaxial Magnetoplasma Accelerator

Abstract

The results of experiments on the initiation of an arc-discharge-like Z-pinch in a coaxial magnetoplasma accelerator in different ways have been considered. It has been found that, with increasing resistance between the electrodes, the switching voltage increases and the time of arc-discharge ignition decreases. The electrophysical parameters of an arc, such as voltage, discharge current, pulse duration, transferred charge, and input energy, are unaffected by the method of initiation of an arc discharge.
