Optical spectra diagnostics in plasma impurities control

The development of methods and measuring devices for plasma impurities identification have been the main goals of the work. The significance of plasma effluents in energetic balance of thermonuclear reactors as well as their potential sources have been discussed. The methods of plasma purity control have been reviewed and the new original solution based on CCD (charged - coupled device) camera with interpretation filters and computer on-line system has been worked out and shown on that background. The application of that measuring system enabled to get quick characteristics of plasma and to identify existing impurities. That has been shown as a results of experiments. 66 refs, 52 figs, 11 tabs
