High-power quartz plasmadynamic source of short-wavelength and vacuum ultraviolet radiation with a brightness temperature ~40 kK

An analysis of possible ways of enhancing the brightness of ultraviolet radiation emitted by quartz light sources led to a proposal of a new lamp in which an electric-discharge plasma is heated as a result of shock-wave thermalization of directional kinetic energy when a high-velocity plasma stream is decelerated in a gaseous medium, which also acts as a filter of the hard component of the plasma emission spectrum. This approach made it possible to construct quartz light sources characterized by an output radiation flux density in the short-wavelength ultraviolet range (180–250 nm) corresponding to the radiation emitted by a black body at a temperature of 40 kK.
