An installation for studying luminescence excited by high-energy charged particles in dense xenon-containing gas mixtures with the possibility of regeneration and repeated use of xenon

Аннотация

An installation for studying the spectral, temporal, and generation characteristics of xenon-containing high-pressure excimer mixtures is described. The mixtures are excited by a pulsed beam of fast electrons with energy Е_e = 220 keV, pulse duration Т_p = 5 ns, and maximum beam current density I_max = 20 A/cm². Spectral and temporal measurements are taken in the wavelength range of 200–1200 nm with a wavelength resolution of 1 nm (the Maya-2000Pro spectrometer) and a temporal resolution of 2 ns/cm (a Tektronics TDS1024 oscilloscope and a FEU-106 photomultiplier tube). To reduce the xenon consumption when carrying out experimental investigations, the installation is equipped with a system of xenon peeling and regeneration, which allows the xenon loss to be reduced by factors of 50–100. The use of one additional external mirror for determining the gain characteristics of high-pressure excimer mixtures upon pumping with fast charged particles is considered.
