Computer-aided diagnostics of an optically dense plasma from absorption spectra
Abstract
An algorithm has been developed for diagnosing an optically dense plasma from the absorption spectra of individual self-reversed lines. The principal parameters used are the absorption line width at 0.8 J0 (where J0 is the transmission radiation intensity) and the absorption profile asymmetry. The problem is solved on a computer using an iteration procedure. The method has been applied to a 2 ms low-voltage discharge, with a time resolution of 0.1 ms.
