Abstract

This paper reports on experimental results obtained during study of the source of UV spontaneous radiation based on high-current pulsed discharge in xenon and krypton being developed for the purposes of influence upon diamond detector. It has been shown that xenon lines have the highest emission spectral density in the UV range of discharge. The energy share of radiation in the range 200-250 nm with respect to the complete radiation energy in the whole control band 200-650 nm versus excitation pulse duration reaches 30-50%. Maximal density of radiation power above 50 kW/cm² in UV range has been registered under xenon pressure of 550-650 Torr. Changing xenon for krypton (argon) lead to double decrease of emission energy. Minimal resistance of 1×3 mm² irradiated diamond crystal, registered at the moment of current maximum in diamond detector circuit is 300.Ω.
