Abstract

Abstract

The cumulative ion saturation currents on a cylindrical probe are measured by using a negatively biased, water-cooled cylindrical electrostatic probe sweeping with a fixed speed perpendicularly across a laminar argon plasma jet, and the radial distribution of local ion saturation current density is then obtained by use of the Abel inversion. The radial distribution of the jet impact pressure is also measured dynamically using a water-cooled pressure probe. Based on the measured profiles of the local ion saturation current density and impact pressure and using related theoretical relations, the radial distribution of the plasma jet temperature is deduced. Additionally, the spectroscopic method based on the relativeintensity of spectral lines is employed to measure the plasma jet temperatu
