兰州重离子研究装置 (HIRFL) 的两个冷却存储环 (CSR) 之间使用了踢脚控制系统进行束流提取和注入。为了满足特殊物理实验的要求，Kicker控制器进行了升级，采用基于ARM+DSP+FPGA技术和单片电路架构设计的新型控制器，可实现2.5 ns的精密延时。 2014年9月，新的踢球控制系统在踢球场安装完毕，并完成了使用该系统的测试实验。此外，控制器提供预触发信号，旨在同步束流诊断系统和物理实验。实验结果表明，没有出现“漏踢”和“低效踢”现象，并且数字化中的踢电源可以单独调整多路触发信号延迟；因此，与原始系统相比，光束传输效率得到了提高。基于新型HIRFL推进器控制系统，成功完成了快速提取和注射实验。
A kicker control system is used for beam extraction and injection between two cooling storage rings (CSRs) at the Heavy Ion Research Facility in Lanzhou (HIRFL). To meet the requirements of special physics experiments, the kicker controller has been upgraded, with a new controller designed based on ARM+DSP+FPGA technology and monolithic circuit architecture, which can achieve a precision time delay of 2.5 ns. In September 2014, the new kicker control system was installed in the kicker field, and the test experiment using the system was completed. In addition, a pre-trigger signal was provided by the controller, which was designed to synchronize the beam diagnostic system and physics experiments. Experimental results indicate that the phenomena of “missed kick” and “inefficient kick” were not observed, and the multichannel trigger signal delay could be adjusted individually for kick power supplies in digitization; thus, the beam transport efficiency was improved compared with that of the original system. The fast extraction and injection experiment was successfully completed based on the new kicker control systems for HIRFL.
