Design and experimental study of a two-dimensional position sensitive X-ray detector

A prototype of a two-dimensional position sensitive X-ray detector was designed and constructed for small angle X-ray scattering experiments at BSFR （Beijing Synchrotron Radiation Facility）. The detector is based on MWPC with cathode strip readout, and has a sensitive area of 200 mm×200 mm. The spatial resolution （FWHM） of about 210 μm along the anode wire direction was obtained from the ^55Fe X-ray test of the detector.
