Abstract
We report measurements of electron temperature and pressures of neutral particles in plasmas of high-pressure Na-Hg-Xe or Na-Cd-Xe arcs. We applied the standard plasma diagnostic techniques developed for the Na-Hg-Xe discharge to the new Na-Cd-Xe discharge lamp. Electron temperature has been calculated from the shape of the sodium recombination continuum at 408 nm in the case of Na-Cd-Xe lamp. The results are compared with the temperature obtained from the shape of self-reversed sodium lines at 568.2 nm and 568. 8 nm. Sodium, mercury and cadmium vapour pressures have been derived from the separation of maxima of self-reversed sodium resonance line.
