圆柱形探测器和平行轴点余弦源定义的立体角的解析计算
Analytical calculation of the solid angle defined by a cylindrical detector and a point cosine source with parallel axes
摘要：
本文导出了在源方向平行于圆柱轴的情况下，有限长圆柱对着余弦角分布点源的立体角的解析表达式。作为辅助结果，在两个盘具有也与源方向一致的公共对称轴的情况下，还提供了在扩展盘源处由盘检测器对向的立体角的表达式。
英文摘要：
We derive analytical expressions for the solid angle subtended by a right finite circular cylinder at a point source with cosine angular distribution in the case where the source direction is parallel to the cylinder axis. As a subsidiary result, an expression for the solid angle subtended by a disc detector at a spread disc source is also provided, in the case where the two discs have a common symmetry axis which is also coincident with the source direction.
