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

摘要

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 E-e = 220 keV, pulse duration T-p = 5 ns, and maximum beam current density I-max = 20 A/cm(2). 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.
