Abstract

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 flux 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.

利用中子活化实验对PHITS模拟代码进行基准测试，以便可靠地计算中子场

本文将金、铟箔的中子活化实验结果与PHITS和PHITS- dchain模拟的活化结果进行了比较。目的是评估这些模拟方法的准确性，以预测此类箔中诱导活性的数量。中子活化实验在德国亚琛应用科学大学使用10 Ci AmBe源进行。通过测量衰变的198Au和116mIn的γ射线能谱，利用现代BEGe探测器确定了其活度。在模拟中，采用两种方法提取活度：直接通量分析和更详细的DCHAIN计算。总的来说，在15%以内的活度一致性很好，这表明PHITS程序对这类实验的核物理输入和中子输运计算是可靠的。
