Abstract

Accurate prediction of radiation fields generated by heavy ion interactions is important in medical applications, space missions, and in design and operation of rare isotope research facilities. In recent years, several well-established computer codes in widespread use for particle and radiation transport calculations have been equipped with the capability to simulate heavy ion transport and interactions. To assess and validate these capabilities, we performed simulations of a series of benchmark-quality heavy ion experiments with the computer codes FLUKA, MARS15, MCNPX, and PHITS. We focus on the comparisons of secondary neutron production. Results are encouraging; however, further improvements in models and codes and additional benchmarking are required.

重离子输运码中子产生的基准测试
对重离子相互作用产生的辐射场的准确预测在医疗应用、空间任务以及稀有同位素研究设施的设计和运行中具有重要意义。近年来,在粒子和辐射输运计算中广泛使用的几个完善的计算机代码已经具备了模拟重离子输运和相互作用的能力。为了评估和验证这些功能,我们使用计算机代码FLUKA、MARS15、MCNPX和PHITS对一系列基准质量的重离子实验进行了模拟。我们着重于二次中子产生的比较。结果令人鼓舞;然而,模型和代码的进一步改进以及额外的基准测试是必需的。
