Gas scintillation proportional counter for x-ray astronomy

Technical Report ·
OSTI ID:7292754
A transparent parallel plate xenon gas scintillation proportional counter was designed and built using ultra-high vacuum technology. This X-ray detector should achieve improved resolution by eliminating the charge multiplication stage. In order to use such a detector for space research it is highly desirable to eliminate any gas flow purification system. A new concept was therefore developed which uses a Ce-getter and does not depend on the presence of wavelength shifters. The preliminary experimental results, which are comparable to that achieved with an ordinary wire gas counter, demonstrate that this new concept is feasible. With a better light collecting geometry, which was deliberately not optimized in this first prototype, significant improvement is possible.
