Abstract
The need to control a high-current pulsed arc with the aim of raising the efficiency of current-induced heating of a gas is theoretically substantiated. A computational formula for the length of the discharge gap in devices where a pulsed arc is initiated in a gas is derived. The effect of arc voltage control on the current dynamics and variation of the voltage across the gap is studied experimentally. It is shown how pulsed arc control influences the propagation rate of the leading edge of a discharge jet generated in a pulsed plasma jet former.
