Helium plasma jet : construction and plasma properties. Morris, Robert Norton

Abstract

A model - of which a similar type was found applicable to an argon plasma jet - is developed and applied to a laminar helium jet operated at atmospheric pressure with a current of 185 amps. The results are used to investigate the equilibrium properties of the plasma. It was found that the helium plasma was not in a state of Local Thermodynamic Equilibrium but that the neutral atoms were considerably colder than the electrons. (Te ≈ 17,000°K; To≈5,700°K) Instructions are given in the thesis on the construction, operation and properties of a d.c. plasma jet.
