Abstract

The main interest of this paper is to study the properties of plasma ejected from a coaxial discharge into an expansion chamber. It has been shown that the velocity of expanded plasma is near to that of sound similar to that of laser - produced plasma from a target. It has been found that the plasma expanded adiabatically in a shell like shape. The temperature and density spatial variation has been presented. The investigations have been carried out for a working argon gas of 0.1 torr pressure at peak discharge current of 38 kA with rise time of 6.2 μs.
