In this work, seven different analytical expressions for the solid angle subtended by a circular detector for a coaxial circular source are compared. These expressions -- which have been published by different investigators over the course of the last half century -- are compared for previously published geometries, and for geometries planned in future experimental work. As compared to benchmark Monte Carlo calculations, the expressions published by Segre, Knoll, and Ruby, were the most accurate and exhibited the highest degree of self-correlation.
在这项工作中,对圆形探测器对于同轴圆形源所张立体角的七种不同解析表达式进行了比较。这些表达式是在过去半个世纪中由不同研究者发表的,针对先前已发表的几何结构以及未来实验工作中规划的几何结构进行了比较。与基准蒙特卡罗计算相比,塞格雷、诺尔和鲁比发表的表达式最为准确,且自相关程度最高。
