中国于2011年启动了加速器驱动次临界系统（ADS）计划，旨在设计和建造一个ADS示范设施，该设施具有超过1000兆瓦的火力发电能力，分多个阶段持续约20年。驱动器的直线加速器被定义为1.5 GeV的能量，10 mA的电流和连续工作模式。为了满足极高的可靠性和可用性，直线加速器的设计有很大的安装裕度和容错能力，包括热备用注入器和关键元件故障的本地补偿方法。加速器复合体由两个平行的10 MeV注入器，联合中能束流传输线，主直线加速器和高能束流传输线组成。除了射频四极加速器（RFQs）是在室温下使用的超导加速结构。本文介绍了驱动器直线加速器的总体设计考虑和束流动力学设计。
An accelerator-driven subcritical system (ADS) program was launched in China in 2011, which aims to design and build an ADS demonstration facility with the capability of more than 1000 MW thermal power in multiple phases lasting about 20 years. The driver linac is defined to be 1.5 GeV in energy, 10 mA in current and in cw operation mode. To meet the extremely high reliability and availability, the linac is designed with much installed margin and fault tolerance, including hot-spare injectors and local compensation method for key element failures. The accelerator complex consists of two parallel 10-MeV injectors, a joint medium-energy beam transport line, a main linac, and a high-energy beam transport line. The superconducting acceleration structures are employed except for the radio frequency quadrupole accelerators (RFQs) which are at room temperature. The general design considerations and the beam dynamics design of the driver linac complex are presented here.
