Spatial Variation of Plasma Parameters in Argon Plasma from a Washer Stacked Plasma Gun

Rita Paikaray ^[3] | Biswambhar Mohanty ^[2]

Abstract: In this communication, spatial variation of ion density and electron temperature of argon, an inert gas, plasma are reported. Plasma is created by using a washer stacked plasma gun. The plasma structure is short lived (~ 1 ms). The square wave pulse fed to gun is only ~ 140s. The measurements are done by using double probe. Ion density is found to be ~ 10 ^17 m-3and electron temperature is ~ 10^3 10^4 K for discharging potential 1 kV. It is observed that both ion density and electron temperature decreases as the distance from gun mouth is increased. Increasing applied voltage both ion density and electron temperature increases.

Keywords: Ion density, electron temperature, plasma gun, double probe
