Diagnostic subsystem of KTM Tokamak radiation losses

Progress in the field of controlled thermonuclear fusion in many respects is determined by development of diagnostic systems of thermonuclear plasma. One of the major problems of diagnostics is practically obtaining the detailed information about radiation losses location during all plasma discharge. In the thermonuclear installations of a Tokamak type the considerable part of power of heating is blown by ruled radiation of impurities-basically in vacuum ultra-violet (VUV) and mild X-ray areas of a spectrum, and the part is blown by neutral fragments. Therefore, it is necessary to measure permanently the local specific power of radiation and total power of radiation losses from plasma, as these values contain the relevant information indispensable for analysis of power and impurities, the availability of which results in radiation losses. The paper discusses a diagnostic system to measure the radiation losses.
