摘　　要：壁电流探测器是观测粒子加速器瞬时束流信息的一种重要手段。中国散裂中子源(CSNS)快循环同步加速器中安装了两个壁电流探测器,其中一个壁电流探测器用来测量束流的微脉冲信息。本文介绍了壁电流测量系统的硬件和软件,鉴于传统示波器在垂直分辨率及存储深度等方面的局限性,提出了一种定制示波器来进行壁电流的信息读取,并利用LabVIEW编程实现了20ms内束流信息的宏脉冲读取及微脉冲结构的分析,使用同步的环高频信息分析能得出快循环同步加速器中双束团关于相位、圈数、每圈束团形状等方面的相关信息。Wall current monitor is a device to observe the instantaneous beam current in particle accelerators.One of the two wall current monitors installed in CSNS rapid cycling synchrotron is used to measure the micro-pulse information of the beam.The hardware and software of current measurement system were introduced in this paper.In response to the limitations of the traditional oscilloscope in terms of vertical resolution and storage depth,a custom oscilloscope was developed to read the wall current information.The analyses of macro-pulse reading and micro-pulse structure in 20 ms were realized by LabVIEW.The high frequency information can be used to analyze the double bunches with respect to phase,number of turns,shape of the bunch per ring in the rapid cycling synchrotron.
