利用FLUKA软件,对10 MeV电子加速器轻量化屏蔽进行模拟优化设计。从屏蔽源项剂量率优化与屏蔽层材料筛选两方面开展研究。结果显示,在束流扫描窗下布放6 cm厚度水的束流接收槽,可使屏蔽源项剂量率降低约33.17%;筛选出的聚乙烯+铅组合屏蔽材料较混凝土屏蔽体能够大幅度节省空间,减小屏蔽厚度,并使屏蔽体重量降低约81.74%。研究成果可为10 MeV工业辐照电子加速器实现可移动化提供技术支持。

The lightweight shielding design of the 10 MeV electron accelerator was optimized and simulated using the FLUKA code.Two separate studies were conducted:optimizing the dose rate of the source term and screening the shielding layer material.The results show that placing a tank filled with 6 cm of water under the electron beam window can reduce the dose rate of the source term by about 33.17％.Compared with the concrete shielding,the lightweight composite shielding material of"polyethylene+lead"can significantly save space,reduce the shielding th...
