• An EGS4 user code is developed to design and optimize gamma-ray detection systems for various types of radiation sources. The code is fundamentally based on the PRESTA-CG, which is the user code introducing the PRESTA algorithm and a combinatorial geometry method. The additional and existing functions are integrated in the present code, and the handling is simplified. The latest techniques related to the calculation of material cross section are also incorporated in the code for the accurate simulation. The main additional functions are classified into two parts of the definition of radiation sources and the photon tracing. The former includes the functions on the simple handling of source geometry and the use of redefined radiation source. In the latter functions, it is possible to estimate the simultaneous events among plural detectors and the trace of photon in the interested regions. The developed user code is applied to detection systems in order to demonstrate its availability. As the result, it is found that the present code allows the detailed response analysis of complicated detection systems for various radiation sources with a simple handling.
