Paper Abstract

Development of a detector for a Bragg spectrometer experiment is described, including the test setup and the read out electronics. A few examples of the position resolution are presented.We have built and put into operation a computer controlled test-stand with: A collimated x-ray beam in the energy range of 0.5 to 6 kev and the width of 50 to 200 microns, an x-y translation table for positioning the detector,a gas system for recirculating and filtering of different gas mixtures and pressures and an electronics system using the charge division method for event position determination. Charge pulses from the detector are digitized and analysed in a micro-processor where the position and energy spectra are stored. Background rejection is determined by energy, position and rise time windows in the micro-processor software.
