兰州冷却储存环重离子研究装置（HIRFL-CSR）的引出和注入系统包括多个部分，其中CSRm引出部分和CSRe注入部分是最重要的部分，其时间控制精度直接影响到束流的注入和引出效率采用FPGA技术对Kicker控制电源系统进行精确控制，控制精度达到ns级，ARM主要用于控制数据的上传和下载，时序控制主要由FPGA上的程序完成，所有控制均通过FPGA实现，实现了对Kicker控制电源系统的精确控制通过光纤传输远程定时信号，同时利用数字电位器对供电系统进行定压，定压精度为0.1%。
The heavy ion research facility at Lanzhou cooler storage ring(HIRFL-CSR) includes several parts of extraction and injection systems.Among these parts the extraction part of CSRm and the injection part of CSRe are the most important parts and the time control precision of them affects the beam's injection and extraction efficiency directly.In this paper the advanced ARM+FPGA technology was applied to make a precise control of the Kicker control power supply system and the control accuracy reached to ns.ARM was mainly used to upload and download the control data and the timing sequence control was mainly completed by the program on FPGA.All the control signal of remote timing was transferred through optic fiber,and at the same time,the digital potentiometer was used to fix the voltage of the power supply system with the given accuracy of 0.1%.
