A diagnostic apparatus has been created for investigating the spectroenergetic characteristics of powerful pulsed plasma radiators in the VUV region. Spectral selection of the radiation is carried out by a set of gaseous and crystalline light filters. The apparatus consists of a diagnostic probe with a pyroelectric photodetector and a vacuum chamber for its energy calibration by means of a Planck radiator based on a capillary discharge. A technique has been developed for spectroenergetic measurements.
