摘要: 硼中子俘获治疗(BNCT)装置由一台ECR离子源、一条低能传输线(LEBT)、一台3.5MeV射频四极加速器(RFQ)、一条高能传输线(HEBT)和一个靶站组成。本文首先介绍了BNCT真空系统的组成,对比了BNCT与CSNS离子源真空系统的差异,给出了HEBT真空系统设计方案和气载计算方法。利用Molflow软件模拟计算了HEBT真空系统的静态压力分布和打靶时的动态压力分布,并与目前运行的真空状态进行比对。

关键词: 硼中子俘获治疗, 真空系统组成, 高能传输线, Molflow, 压力分布

Abstract: The boron neutron capture therapy(BNCT) device consists of an ECR ion source, a low energy transmission line(LEBT), a 3.5 MeV radio frequency quadrupole accelerator(RFQ), a high energy transmission line(HEBT)and a target station. The article first introduces the composition of the BNCT vacuum system, compares the differences between the BNCT and CSNS ion source vacuum systems, and gives the HEBT vacuum system design scheme and gas production calculation method. Using the Molflow software, the static pressure distribution of the HEBT vacuum system and the dynamic pressure distribution during beam bombardment are calculated and compared with the current vacuum state.

Key words: boron neutron capture therapy, vacuum system composition, high energy transmission line, Molflow, pressure distribution
