RADIATION TEMPERATURE MEASUREMENT OF ARGON ARC PLASMA BY SUBMILLIMETER DIAGNOSTIC TECHNIQUES

Abstract
Methods of radiation temperature measurement of the plasma filament by active and passive submillimeter diagnostic are described. The profiles of the side-on brightness of plasma thermal emission are measured at two wavelengths, one of them being selfabsorbed. These data are used to determine the radiation temperature and optical depth of plasma [1]. Simultaneous probing of the plasma filament by submillimeter radiation at two wavelengths allows to check this method and find out the degree of plasma equilibrium as well as the nature of electron collisions.
