Abstract
An experiment to measure the electron density and temperature in a low‐density reflex discharge in helium, by scattering of cw argon‐ion laser radiation at 4880 Å, has been successfully carried out. A synchronous detection scheme was used to distinguish the scattered radiation from all other radiation entering the detector. The scattering measurements indicated a density of 4.8×1018 m−3 and a temperature of 1.2 eV. These values are in good agreement with those obtained with a Langmuir probe.This publication has 7 references indexed in Scilit:
