Paper Abstract

The light yield, or electroluminescence yield, of pure xenon for reduced electric fields below the ionization threshold (about 6 Vcm-1torr-1) was measured for pressures of 825, 570 and 276 torr using a uniform field gas proportional scintillation counter excited with 5.9 keV x rays. A linear behavior was exhibited from the 1 Vcm-1torr-1 electroluminescence threshold, but the measured yield (for lambda greater than 165 nm) diminished with the gas pressure. The best energy resolution obtained was 7.6% for collimated 5.9 keV x rays with xenon at 825 torr. A Fano factor of 0.26 was measured for the three xenon pressures.
