A plasma was generated in a helium-hydrogen mixture at a pressure of 18 mm of Hg between two periodically (10 kHz) repolarized ferroelectric ceramic plates. Profiles of two HeI- and the H β-lines were measured with spectrometers of different resolutions. For the narrowest line, an interferometric method was applied. The gas temperature ( T g = 480 K) was determined from the Gaussian width of the deconvolved Voigt profile of the HeI 501.6 nm line. The electron temperature ( T e ≈ 16,000 K) was estimated from the line intensities applying appropriate plasma models and the electron density ( n e = 1.4 × 10 14 cm -3) was derived from the half width of the Stark-broadened H β-line.
