Abstract

A prototype Xe + 10% CH4 microstrip detector was used to study the K-edge discontinuity in the pulse-height distribution as a function of the energy of incident X-rays. The electronics used was such that a pulse-shape rejection could be made of K-fluorescence reabsorption in the detector. The measured jump at the K-edge was (169 +/- 12)eV. It was also seen that K-alpha- and K-beta-decay channels produce different pulse heights for the same deposited energy. We find that the difference in energy between the calibration fines of the K-beta 2- and the K-beta 1.3-escape peaks is (93+/-12)eV whereas between the K-beta 1.3 and the K-alpha-escape peaks' calibration the energy gal is (69+/-7)eV.
