Abstract :
The performance of a xenon-filled gas proportional scintillation counter instrumented with a microstrip plate covered with KI and KBr films as photocathodes to detect the VUV Xe scintillation light is reported. The results for its energy resolution and detector gain for 5.9 keV X-rays are presented and compared with previous results obtained with a CsI film deposited on the microstrip plate under the same conditions. Its performance was studied as a function of the halide film thickness and the scintillation region length. The best energy resolutions obtained reached values of 11.4% and 14.9% for KI and KBr, respectively.
