摘要
用基本Monte Carlo方法计算了圆面探测器对均匀非严格平行圆面源(两圆面中心轴线相交成α度)的几何因子,并且与圆面探测器对均匀同轴圆面源的几何因子进行了比较,探讨了两圆面中心轴线间夹角α对几何因子的影响;为了检验本文方法及所编程序的好坏,选取α=0时的数据与多边形近似法进行了比较。并根据讨论的结果,提出了对实验操作的要求。
Geometry efficiency of disc detector to disc source in the situation, which α≠ 0（the angle from axis of detector and axis of source is called as α）, is calculated by basic Monte Carlo method, and then compared with that of disc detector to disc source in the case that α = 0. We also investigate the influence of the angle a from two axes on the geometry efficiency. According to the discussion results, the experimental operation requirement has been proposed.
