摘要：

A simple, inexpensive, high-performance gas proportional scintillation counter for x-ray spectrometry is described. Energy resolutions below 9% are obtained with detector window diameters of less than 22 mm, for 5.9 keV Mn fluorescent x-rays, even for a small window-to-sample distance where beam collimation is not effective. X-ray fluorescence spectra are presented for biotite, pyrite/chalcopyrite and stainless-steel samples.
