中国散裂中子源加速器质子束流加速能量为1.6GeV,重复频率为25 Hz,撞击固体金属靶产生散射中子,一期工程的打靶束流功率为100kW。直线加速器的设计束流流强为15 mA,输出能量为81MeV。射频加速和聚束系统包括一台射频四极场加速器、中能束流传输线的两个聚束器、四节漂移管直线加速器加速腔和直线-环束流传输线的一个散束器,与之相对应,共有8个单元在线运行的射频功率源为其提供所需的射频功率。目前,直线射频功率源系统预研项目已全部完成,各项性能参数均已达到设计指标,当前正处在批产安装调试阶段。
The proton beam acceleration energy of China spallation neutron source accelerator is 1.6 GeV and the repetition frequency is 25 Hz. The scattered neutron collides with the solid metal target, and the target beam power of the first stage project is 100 kW. The linac design beam current is 15 mA and the output energy is 81 MeV. The RF Acceleration and Beam Binding System consists of a RF quadrupole accelerator, two beam-borescopes for a medium-energy beamline, a four-section drift-tube linac and a beamsplitter for a line-to-ring beamline Correspondingly, a total of eight units of RF power sources operating on-line to provide the required RF power. At present, the pre-research project of linear RF power source system has been completed and all the performance parameters have reached the design specifications. Currently, it is in the process of batch installation and commissioning.
