摘　　要：束流位置探头电中心相对于邻近四极磁铁磁中心的位置偏移，可以通过基于束流的准直技术加以确定，其准直精度可以比用传统的准直方法提高一个数量级．介绍了基于束流的准直的基本原理和在ＢＥＰＣ储存环上的初步实验结果，以及对今后进一步开展该项实验研究的设想．The offset of the beam position monitor (BPM) with respect to the magnetic center of the quadrupole can be determined by the method of the beam-based alignment. The BPM alignment accuracy can be improved by one order of magnitude compared with conventional surveying techniques. This paper gives a brief intreduction to the principle of the beam-based alignment and the description of the preliminary experiment performed on the BEPC storage ring. The considerations of the further experiments are also given.
