Benchmarking of the PHITS simulation code using neutron activation experiments for reliable calculations of neutron fields
- In this study, experimental results from neutron activation of gold and indium foils are compared with the activation simulated using PHITS and PHITS-DCHAIN codes. The aim was to evaluate the accuracy of these simulation methods for predicting the amount of induced activity in such foils. Neutron activation experiments were carried out using a 10 Ci AmBe source at the University of Applied Sciences Aachen in Germany. Activities were determined using a modern BEGe detector by measuring the γ-ray spectra of decaying 198Au and 116mIn. In the simulation, two methods were used to extract the activities: a direct fux analysis and a more detailed DCHAIN calculation. Generally, very good agreement of the activities within 15% is observed, which shows the reliable nuclear physics input and neutron transport calculation of the PHITS code for these kinds of experiments.
