摘要：

A gas scintillation proportional counter has been developed for measuring ultrasoft fluorescence x rays. This counter is high-vacuum compatible for connecting to the ICF-70 flange of a vacuum chamber. A Mylar window of 0.6-mum thickness and 12-mm diameter is utilized for the entrance of the ultrasoft x rays. The counter has a large entrance window of approximately 100 mm2 and an energy resolution high enough to separate C Kalpha and 0 Kalpha radiations. This counter is applicable to not only x-ray fluorescence analysis, but also to fluorescence-yield extended x-ray absorption fine structure measurement of ultralow-Z elements.
