Abstract:

Preliminary experiments were performed to determine the feasibility of measuring temperature in an argon theta pinch tube by the two-line ratio method. Calculations were made showing the temperature errors to be expected and the degree to which various types of thermal equilibrium exist as a function of time and electron density. Time integrated spectrograms were taken and a number of argon II lines were identified for which gf-values are known. Densitometer traces of the films indicated that the line shapes are suitable for the two-line method and an approximate calculation was made indicating a temperature of 35,000K. It was concluded that time resolved measurements would be desirable. Author
