Abstract

A Gas Scintillation Counter (GSC) with high background rejection capability, fast timing char-acteristics and good energy resolution has been developed for quasimolecular X-ray spectroscopy in inelastic heavy ion - atom collisions. The detector presented in this paper consists of a high pressure Xe-filled absorption cell and a secondary scintillation parallel gap. Highly efficient de-tection of the primary light provides a time resolution of 3 ns (FWHM). The energy resolution is 4.3% (FWHM) for 60 keV X-rays. A rejection efficiency of 92% for Compton background in the energy range between 35 and 160 keV is obtained by applying the K - fluorescence gating method and pulse-shape analysis, to the secondary scintillation pulse.
