A compact pyrodetector for measuring the radiation energy of pulsed plasma light sources in the vacuum ultraviolet

摘要

A compact noise-resistant pyroelectric calorimeter has been developed in which radiation is spectrally selected by quartz and inert-gas filters. The calorimeter is intended both for measuring the spectroenergetic characteristics of powerful pulsed plasma radiators and for measuring the surface irradiance of test objects in a 2π-sr solid angle. The calorimeter has been calibrated in energy, and the results have been confirmed by thermocouple measurements.
