文摘
We present and evaluate a program for the semi-empirical calculation of the full-energy peak efficiency of a hyper-pure germanium detector, by using the efficiency transfer method. Using simple Monte-Carlo integration and constructive solid geometry, we are able to calculate the effective solid angle for a wide range of HPGe detector and sample geometries. However, the main advancement is including in our calculations the inhomogeneity of the sample activity, caused by the inhomogeneous neutron flux when performing neutron activation analysis (NAA). This reduces systematic error in the standard procedure of NAA. To increase usability, the input and output file formats used are compatible with the program SOLANG, which belongs to the Kayzero for Windows (KayWin®) software.
