Spectroscopic Studies of High Pressure Argon Plasms

Abstract
Results of spectroscopic investigations on high pressure argon arcs are presented. The experimental investigations were performed on cascade arcs at pressure levels up to 250 atm. Measurements of the radial temperature distribution as well as of the width and shift of selected spectral lines were performed. Results concerning the AI 4300 line are presented. A comparison with theoretical values shows fair agreement.
