使用粒子加速器的紧凑型中子源是用于材料分析、基础设施诊断、裂变材料检测和医学应用的有前途的工具。为了对老化混凝土和钢筋的退化进行非破坏性的现场检查，必须开发一种轻便紧凑的中子源系统。为了设计一个更紧凑的便携式中子源用直线加速器，我们研制了一个500 MHz的直线加速器，本文描述了一个紧凑型中子源用直线加速器的设计。首先，利用束流跟踪模拟软件，设计了500 MHz质子直线加速器的单元参数，该加速器可以将质子束流从30 keV加速到2.49 MeV。然后，利用三维电磁场仿真软件和多物理场仿真软件对500 MHz超导直线加速器的谐振腔进行了优化设计，并对带冷却通道的谐振腔的热特性进行了研究。
A compact neutron source using a particle accelerator is a promising tool for material analysis, infrastructural diagnostics, fissile material detection, and medical applications. For non-destructive, on-site inspection of the degradation of aged concrete and steel reinforcement it is essential to develop a light and compact neutron source system. To design a more compact RFQ linac for a transportable neutron source, we developed a 500 MHz RFQ linac.In this paper the design of a 500 MHz RFQ linac for a compact neutron source is described. First, using beam tracking simulation software, we designed the cell parameters of the 500 MHz RFQ linac, which can accelerate a proton beam from 30 keV to 2.49 MeV. Then, using three-dimensional electromagnetic simulation software and multiphysics simulation software, we optimized the cavity design of the 500 MHz RFQ linac, and investigated the thermal properties of the cavity with the cooling channels.
