摘要
本文介绍 JJ-2型静电加速器机房和辐照室的屏蔽设计。文中叙述了屏蔽的对象、屏蔽设计的依据、屏蔽计算方法和屏蔽方案。实测结果表明,在加速器电压2MV、束流强度0.2mA 运行条件下,辐照室四周墙外侧附近的辐射水平为30—40μR/h。从屏蔽防护的角度,为该加速器今后工作的发展留出了余地。
The shielding design of JJ-2 model electrostatic accelerator hall and irradiation room ispresented in the paper.The shielding information such as shielding objects,design basis,calculationmethod and shielding scheme is described.The measurement results show that the radiation level nearoutside walls of the irradiation room was 30—40μR/h when the accelerator was operated at 2MV and0.2mA.The is to allow future research development for the accelerator from the point of view of radi-ation protection.
