摘　　要：SGS装置中合适的准直器结构可以提高系统的探测效率并降低串扰。运用MC法对不同形状和尺寸的准直器建模,模拟实际的SGS装置的测量过程。根据准直器的设计准则,对比了几种SGS准直形状的各自特点,并在实际的装置上验证了模拟计算的正确性,为SGS探测系统设计提供参考。A suitable collimator shape in the SGS device can increase the detection efficiency of the system and reduce crosstalk.The MC method is used to model the collimators of different shapes and sizes to simulate the measurement process of the actual SGS device.According to the design criteria of the collimator,the characteristics of several SGS collimated shapes are compared,and the correctness of the simulation calculation is verified on the actual device,which provides a reference for the design of SGS detection system.
