ABSTRACT
We present the results of a spectroscopic study of hydrogen Balmer line shapes and intensities in a microwave-induced discharge generated in an Evenson resonant cavity at 2.45 GHz in pure hydrogen and hydrogen-argon and hydrogen-helium gas mixtures. The Balmer line shapes do not show signs of excessive Doppler broadening. The discharge parameters—Doppler temperature (980 K), electron excitation temperature (1460–1790 K), and electron density of about 8×1011 cm-3—point to a typical microwave-induced discharge.
