摘　　要：本文介绍了星载闪烁探测器ＮａＩ（Ｔｌ）晶体和荷电粒子屏蔽塑料闪烁体（ＰＳ）一体化设计，它与国外同类探测器的区别在于，无需外加光电倍增管单独记录塑料闪烁体的反符合信号，从而简化了探测器结构，节省了重量和功耗，获得了较好的屏蔽效果。同时给出了甄别电路有关参数、二重符合μ子望远镜定标方法和反符合效率。A merge into an organic whole design of charged particles rejection as well as the calibration with Muons of cosmic ray were described in this paper. It is differnt from the same kind of detector abroad, and is not necessary to add a photomultiplier to record the anticoincidence signal of the plastic scintillator.Thus, the detector structure can be simplified and the power is economized. At the same time, this model has more anticoincidence efficiency to the charged particles rejection.
