AI 中文摘要
本文详述了近期在国家同步辐射光源二期（NSLS-II）使用蒙特卡罗（MC）粒子输运代码 FLUKA 进行的部分放射学研究。具体而言，评估了预期中的 NSLS-II 设施升级所带来的辐射防护挑战，并考虑了多种升级方案。同时，评估了使用不同屏蔽材料以及采用环境剂量 H* 作为外部辐射暴露有效剂量估算器的影响。最后，展示了同步辐射输运在计算机模拟光束线中的应用，从辐射源到终端站全程利用 FLUKA 最新的 X 射线反射率功能。
英文摘要
This work details some of the recent radiological studies performed at National Synchrotron Light Source II (NSLS-II) using the Monte Carlo (MC) particle transport code FLUKA. In particular, it assesses the radiation protection challenges posed by the anticipated NSLS-II facility upgrade, taking into consideration various upgrade options. Also, it evaluates the impact related to the use of different shielding materials and the employment of ambient dose H* as the external radiation exposure estimator of effective dose. Lastly, a demonstration of synchrotron radiation transport is provided for an in-silico beamline, all the way from the radiation source to end-station, utilizing FLUKA's recent X-ray reflectivity capabilities.
