Abstract

After a brief literature survey, the principle of the measuring system is described. This double-beam system is capable of producing highly resolved profiles of the line He 501.5 nm, which originates from both a hollow cathode cooled with liquid nitrogen and a stabilized spectral lamp. A calculation method has been developed to increase the precision of the measurements of the halfwidth of the He line. The gas kinetic temperature was calculated from the Dopplcr broadening. The results, presented graphically, give the dependence of the gas kinetic temperature from the plasma radius (0-5 mm) and from the carrier gas pressure (66-666 Pa), in both cases at different currents (30-120 mA). Finally theoretical explanations of the results are given.
