Abstract:

A unique method was formulated mathematically for inverting the integral equation relating the integrated spectral intensity to the internal emission coefficient for any general geometry of an optically thin plasma. The method, specialized to the case of one mirror plane of symmetry, was programed for the IBM 7090 and properly tested by means of assumed analytical models. To demonstrate the practical nature of the inversion method as a research tool it was used to measure, for the first time, the absolute emission coefficient of the 6965 wavelength atomic spectral line emitted by the 400 ampere argon arc when distorted by a 36 Gauss external magnetic field. The computer program and test sample are included in the report. Author
