摘要 束流位置监测器(BPM)和与其相邻的四极铁之间的电偏移对于电子储存环轨道校正十分重 要。改变四极铁的强度,并通过测量轨道变化就能够计算出该四极铁的磁中心相对于相邻的BPM的电中心 之间的偏差。基于NSRL储存环的BBA硬件系统和EPICS控制系统,采用Labview平台开发出了BBA测量 的软件控制程序。由计算机控制四极铁的强度,连续测量后拟合得到四极铁的磁中心与相邻BPM的相对偏 差,测量精度可以达到100μm。 To correct the beam orbit in the storage ring, it is required to measure offset of every quadrupole's magnetic center relative to electrical center of its adjacent beam position monitor (BPM). By varying individual quadrupole magnet strength, the offsets could be calculated from the corresponding effects on the beam orbit. A program, which based on the hardware of BBA in HLS storage ring and EPICS, was developed with Lab View 6.1 on Windows system to control the measurement. The program manages quadrupole magnet strength, and performs a least squares fit of the result data points to a parabola, which indicates the offset, i.e. position of quadrupole magnetic center. These offsets were measured with an accuracy of better than 100 μm.
