介绍了基于束流准直(BBA)的工作原理和系统组成,给出合肥800MeV储存环束基磁中心的测量结果,并以束基磁中心作为参考轨道,进行了全环校正。校正之后,剩余轨道的误差可以被控制在±0.1mm之内。
The working principle and system composition based on the beam alignment (BBA) are introduced. The measurement results of the magnetic center of the cluster ring of Hefei 800MeV storage ring are given. The whole ring correction is carried out using the beam base magnetic center as the reference track. After correction, the remaining track error can be controlled within ± 0.1mm.
