چکیده
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.

We derive analytical expressions for the solid angle subtended by a circular disc at a point source with cosine angular distribution (f(μ) = μ) under the sole condition that the disc lies in half-space illuminated by the source (μ ≥ 0). The expressions are given with reference to two alternative coordinate systems (S and S’), S being such that the z axis is parallel to the symmetry axis of the ...

متن کاملCalculation of Source-detector Solid Angle, Using Monte Carlo Method, for Radioactive Sources with Various Geometries and Cylindrical Detector
In this paper source-detector solid angle calculation has been studied by Monte Carlo method, and a computer program is represented. Since most experimental works in nuclear physics are done by using of cylindrical detectors, the solid angle of this type of detector is calculated for various sources. The source in various shapes of a point, cylinder, sphere, or rectangle, may be located in any ...
