Abstract
The feasibility of using UV-sensitive Large Area Avalanche Photodiodes (LAA PD) as the photosensor in xenon Gas Proportional Scintillation Counters (GP SC) is investigated. It is shown that the LAAPD can successfully replace th e photomultiplier tube as the UV photosensor of GPSCs without degradation o f the detector energy resolution, enabling the development of compact GPSCs . Energy resolutions of 7.9 % and 4.4 % are obtained with a xenon-filled GP SC for 5.9 and 22.1 keV X-rays, respectively. (C) 2000 Elsevier Science B.V . All rights reserved.
