Abstract：
When hard X-ray is detected by a multiwire proportional chamber filled with Xe or Kr,the intrinsic K-fluorescent photon,which of ten escapes from the original cell and is absorbed in other cell of the chamber,provides an accomtanied signal with certain amplitude.A processing technique of such signal,called escape gating technique,can improve both the energy resolution and background rejection efficiency of the detector.In this paper,we describe this technique and its application in our balloon borne hard X-ray spectroscope successfully launched on 31 August,1987,at an altitude of 37 km above sea level near Beijing.
