摘要：
A simple high performance pulse shape analyzer has been developed for the astronomical hard X-ray (20-300 keV) experiment LAPEX. The telescope makes use of 16 phoswich detectors of NaI(Tl)/CsI(Na) scintillator crystals. The pulse shape analyzer is based on 16 pairs of shaping amplifiers - one pair for each detector - and one digital electronic chain for calculation of an amplitude ratio, the pulse shape parameter. We describe the mathematical basis of the pulse shape analyser and the functions of its main circuit blocks. Both laboratory and in-flight data demonstrating the good performance of the circuits are presented.
