踢脚系统在环形加速器的光束提取和注入中发挥着重要作用。兰州重离子研究装置 (HIRFL) 的推进系统用于两个冷却储存环 (CSR) 之间的束流提取和注入。该系统由两部分组成：一部分用于从 CSR/main (CSRm) 中提取光束，另一部分用于将光束注入到 CSR/experimental (CSRe) 中。为了满足特殊物理实验的要求，我们对踢脚控制系统进行了升级。在这个升级的系统中，由于每个束束都与射频信号同步，因此可以通过实时测量射频（RF）信号的相位来确定束束的位置。数字时序控制和延迟调节功能基于ARM+DSP+FPGA技术的全新设计，精度达到2.5 ns，比旧系统5 ns的精度有显着提升。此外，该系统还表现出较好的抗干扰能力。此外，还可以提高光束提取效率，参考电压设置的精度可以低至0.1%，而旧系统的精度为2%。
A kicker system plays an important role in beam extraction and injection for a ring-like accelerator. The kicker system in the Heavy Ion Research Facility in Lanzhou (HIRFL) is used for beam extraction and injection between two cooling storage rings (CSRs). The system consists of two parts: one part is used for beam extraction from the CSR/main (CSRm), and the other is used for beam injection into the CSR/experimental (CSRe). To meet the requirements of special physics experiments, we upgraded the kicker control system. In this upgraded system, the position of the beam bunches can be determined by measuring the phase of the radio frequency (RF) signal in real time because each beam bunch is synchronized with the RF signal. The digital timing control and delay regulatory function, which are based on a new design using ARM+DSP+FPGA technology, achieved a precision of 2.5 ns, which is a significant improvement over old system's precision of 5 ns. In addition, this system exhibits a better anti-interference capability. Moreover, the efficiency of beam extraction can be enhanced, and the accuracy of the reference voltage setting can reach as low as 0.1%, compared to 2% for the old system.
