Spectroscopic measurements of electron densities and gas temperatures in deuterium lamps
Abstract:
Plasma diagnostics results of electron densities and gas temperatures in commercial low-pressure deuterium lamps at current densities from 38 A/cm(-2) to 306 A/cm(-2) are presented. These plasma parameters are obtained by comparing measured and calculated Balmer line profiles, taking into account Stark broadening, Doppler broadening, and the influence of fine structure and the apparatus profile. Results for the plasma spot show a steady increase of electron density from 1.6 x 10(13) cm(-3) to 5.0 x 10(13) cm(-3) and of gas temperature from 1800 to 6800 K.
