在过去。几十年来，在亚洲、欧洲和北美已经开发了大规模的国家中子源。作为对这些努力的补充，已经提出了主要为大学和工业研究所服务的紧凑型强子束复合体和中子源，最近已经建立了一些。为了满足中国对脉冲中子/质子束平台的需求，这些平台致力于为多个学科的用户进行基础和应用研究，从材料表征到强子治疗和射线照相，再到用于核废物嬗变的加速器驱动次临界反应堆系统（ADS），我们已经开始建造一个紧凑但可扩展的加速器复合体-紧凑型脉冲强子源（CPHS）。它包括一个加速器前端（一个高强度离子源，一个3 MeV射频四极直线加速器（英语：Radio-frequency quadrupole linac）（英语：Radio-frequency quadrupole linac）（英语：Radio-frequadrupole linac）（英语：Radio-frequadrupole linac））（英语：Radio-frequadrupole linac）（英语：Radio-frequadrupole linac）（英语：Radio在未来，CPHS还可以作为质子治疗和放射摄影环的注射器，或作为ADS测试设施的前端。在本文中，我们描述了CPHS技术系统的设计和预期的操作。
During the past. decades, large-scale national neutron sources have been developed in Asia, Europe, and North America. Complementing such efforts, compact hadron beam complexes and neutron sources intended to serve primarily universities and industrial institutes have been proposed, and some have recently been established. Responding to the demand in China for pulsed neutron/proton-beam platforms that are dedicated to fundamental and applied research for users in multiple disciplines from materials characterization to hadron therapy and radiography to accelerator-driven sub-critical reactor systems (ADS) for nuclear waste transmutation, we have initiated the construction of a compact, yet expandable, accelerator complex-the Compact Pulsed Hadron Source (CPHS). It consists of an accelerator front-end (a high-intensity ion source, a 3-MeV radio-frequency quadrupole linac (RFQ), and a 13-MeV drift-tube linac (DTL)), a neutron target station (a beryllium target with solid methane and room-temperature water moderators/reflector), and experimental stations for neutron imaging/radiography, small-angle scattering, and proton irradiation. In the future, the CPHS may also serve as an injector to a ring for proton therapy and radiography or as the front end to an ADS test facility. In this paper, we describe the design of the CPHS technical systems and its intended operation.
