摘要
BEPCⅡ加速器的束流位置测量系统(BPM)模拟电子学经过十余年的运行逐渐老化,故障率上升,亟需进行升级改造。本文根据该需求,自行设计了基于BEPCⅡ系统参数的数字BPM电子学系统,内容包括模拟信号处理电子学、数字信号处理电子学、BPM固件算法逻辑、数据获取软件以及系统测试等多个部分。设计的数字BPM电子学系统经实验板级性能测试、实验室系统测试以及在线束流测试,结果表明该系统能满足BEPCⅡ装置对束流位置测量的需求。
Beam position monitor(BPM) analog electronics of BEPCⅡ accelerator has gradually deteriorated after more than ten years of running, and the BPM break down rate is rising, which makes it necessary to upgrade the hardware. In this paper, the digital BPM electronics system was developed according to the BEPCⅡ’s parameters, which included the analog part, the digital part, the firmware of algorithm, the software and the testing logic. The digital BPM passed the single board testing, laboratory joint testing and online testing with the real beam, and the results show that the BPM meets the BEPCⅡ machine’s requirements well.
