A SPECTROSCOPIC METHOD OF MEASURING ELECTRON DENSITY IN A SHOCK WAVE INDUCED ARGON-HYDROGEN PLASMA,

Abstract

A technique for the time-resolved measurement of electron density in a shock-heated argon-hydrogen mixture utilizing the Stark broadening of the hydrogen beta line (4861 A) is described. Descriptions of experimental apparatus, procedures, and preliminary results are given for measurements made at the stagnation point of a blunt body and in the region behind the incident shock for Mach numbers between 8.8 and 11.6. Preliminary results show that time-resolved electron density measurements can be made using this technique but that calibration technique must be improved. (Author)
