Abstract
X-ray spectrometric performance of an argon-filled proportional counter containing a 2 mol % xenon additive have been studied. The energy resolution was checked by measuring the X-ray fluorescence and by detecting monochromatic radiation from a 241Am radionuclide. The small addition of xenon results in a reduction in the working voltage from 1500 to 800 V, improvement of the resolution, and a more than twofold increase in the efficiency of detection for photons with energies above the absorption K-edge of xenon.
