Temperature distributions are determined in a helium plasma, the power used being 27 kW and the gas flow rate 7.2 g/minute. Pressure conditions for the plasma under study are respectively 760 and 300 mm Hg. The spectroscopic method used for obtaining temperatures is that of Larenz or the method of maximum emission, applied to the 3,889 Å neutral helium line. A maximum temperature, on the plasma axis, of approximately 24,000° K is obtained.
