The helium ion temperature in a sheet plasma has been determined spectroscopically as the functions of experimental variables such as the gas flow rate and a discharged current in the discharged region of a DC discharge linear plasma machine, i.e., TPD-Sheet III. It is found from experimental results that the experimental variables selected out do not affect a rise in helium ion temperature within experimental errors. It is, thus, presumably true that the decrease in gas flow rate and/or the increase in the discharged current are associate with the increase in number density of helium ion in the sheet plasma unless the rise in helium ion temperature.
