束流位置测量系统不仅可以提供束流位置监测，还可以用于全局轨道校正，以降低波束损失风险，最大限度地提高验收。束流位置监测器(BPM)沿同步加速器安装，通过前端电子和数据采集系统(DAQ)获取束流位置。为实现兰州重离子研究装置(HIRFL-CSRm)主重离子同步加速器和冷却储存环(HIRFL-CSRm)的高精度轨道测量，对BPM及其DAQ系统进行了一系列的对准和标定工作。本文根据所开发的算法和硬件，分析了在实验室以及在BEAM上进行的测试。对采集到的BPM原始数据设计并实现了多种滤波算法，对波束位置和分辨率进行了计算和分析。结果表明，采用新设计的滤波算法后，定位精度由原来的100%以上μm提高到了50%μm左右。根据对测量结果的分析和即将到来的物理要求，提出并讨论了基于现场可编程门阵列(FPGA)技术的CSRM BPM数据采集系统的进一步升级方案。
Beam position measurement system can not only provide the beam position monitoring, but also be used for global orbit correction to reduce beam loss risk and maximize acceptance. The Beam Position Monitors (BPM) are installed along the synchrotron to acquire beam position with the front-end electronics and data acquisition system (DAQ). To realize high precision orbit measurement in the main heavy ion synchrotron and cooling storage ring of heavy-ion research facility in Lanzhou (HIRFL-CSRm), a series of alignment and calibration work has been implemented on the BPM and its DAQ system. This paper analyzed the tests performed in the laboratory as well as with beam based on the developed algorithms and hardware. Several filtering algorithms were designed and implemented on the acquired BPM raw data, then the beam position and resolution were calculated and analyzed. The results show that the position precision was significantly improved from more than 100 μm to about 50 μm by implementing the new designed filtering algorithm. According to the analyzation of the measurement results and upcoming physical requirements, further upgrade scheme for the BPM DAQ system of CSRm based on field programmable gate array (FPGA) technology was proposed and discussed.
