| 摘 要： | 强流重离子加速器（HIAF）是中国科学院近代物理研究所自主研制的一台高能强流重离子加速器，它可以实现p到U的全离子加速。为了保证HIAF运行时的辐射安全，针对该装置的增强器（BRing）及高能外靶实验终端，利用蒙特卡洛程序FLUKA及外推法计算得到了加速p，C及U三种离子时所需的辐射屏蔽。结果表明，加速质子时所需屏蔽厚度最大，并以此为依据给出了全地下结构的屏蔽设计。在此基础上，提出了一种估算高能质子/重离子加速器束流均匀损失时横向屏蔽厚度的方法。结果显示，估算结果与FLUKA计算结果符合较好，验证了该方法的有效性和准确性。High Intensity heavy-ion Accelerator Facility (HIAF) is designed by the Institute of Modern Physics, Chinese Academy of Sciences, which can accelerate particles from proton up to uranium. To guarantee the radiation safety of HIAF during operation, the FLUKA code and extrapolation method were adopted to calculate the shielding thickness. The calculations were based on proton, carbon and uranium particles when losing on the Booster Ring (BRing) and the high-energy experimental terminal. The results indicate that the shielding thickness required for accelerating protons was the largest. Basing on the results, a method for estimating the lateral shielding of a high-energy proton/heavy-ion accelerator was proposed. A good agreement shows between the estimated results and the FLUKA calculated results, the validity and accuracy of the method were verified. |
