Abstract

The 300 MeV proton and heavy ion accelerator complex, which is the key part of SESRI (Space Environment Simulation and Research Infrastructure) project, is currently under construction in China. It comprises an 18 GHz high charge-state ion source, a 108.48 MHz cascaded linac injector consisting of a four-rod RFQ and three interdigital H-mode drift tube linacs, a compact synchrotron, and three irradiation terminals. The extensive ion species from proton to ²⁰⁹Bi $^{32 +}$ will be injected into the synchrotron using multi-turn injection method. The third-order resonance and RF-knockout extraction scheme is adopted to provide quasi-continuous spill for irradiation experiments. The general design of the accelerator complex and simulation results are discussed in this paper.

用于中国SESRI项目的300MeV质子和重离子加速器复合体

300MeV质子和重离子加速器复合体是SESRI（空间环境模拟与研究基础设施）项目的关键部分，目前正在中国建设中。它包括一个18GHz高电荷态离子源、一个108.48MHz级联直线加速器注入器、一个紧凑型同步加速器和三个辐照终端，该注入器由四棒RFQ和三个叉指H型漂移管直线加速器组成。从质子到209Bi32+的大量离子物种将使用多圈注入方法注入同步加速器。采用三阶共振和射频敲除提取方案，为辐照实验提供准连续溢出。本文讨论了加速器复合体的总体设计和仿真结果。

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
