It designs a new type of the electrostatic collection SSNTD(Solid State Nuclear Track Detector) , simulates and calculates the detecting process through a model build by Monte Carlo method, and quantitatively simulates the effects of electrostatic collection method improving detection efficiency. It makes the detector' s potency achieve maximum by simulating and optimizing its size. It is indicated that the conversion fraction which is an optimized object approximately linear grows with the detector' s diameter' s growing, and when the detector's radius reaches 2 cm, the conversion fraction grows gradually, while when the detector's radius reaches about 3 cm, the conversion fraction doesn't grow, and has the dropping trend. It can conclude that when the detectors radius is about 3 cm, the detector has higher detection efficiency.%设计了一种新型的基于静电收集的固体核径迹探测器,并利用蒙特卡罗方法对其尺寸进行优化模拟,确定最优尺寸使装置达到效能最大化,结果表明转换系数作为优化对象随着探测器直径的增大而近似线性增加,当管子半径增大到2 cm后曲线逐渐变缓,而后在约等于3 cm处转换系数基本不再增加甚至有下降的趋势,由此可得出结论探测器半径取3 cm左右时能得到较高的探测效率.
