Position-sensitive X-ray detector

Abstract We have constructed a single anode wire position sensitive gas proportional detector with a fwhm of 80 μm for a highly collimated monochromatic beam of 8 keV photons over a useful range of 38 mm, operated with 600 Torr Xe/CH 4 . The transfer function of the detector has been measured and explained by the theoretical charge distribution induced on the cathode.
