摘　　要：正电子磁通压缩装置(FluxConcentrator,简称磁号)是正电子束流横向发射度的匹配装置,对提高正电子的俘获效率起非常关键的作用,是BEPCⅡ正电子源的重要组成部分.结合磁号的设计加工,用计算机软件模拟了磁号的磁场分布和共振特性,并同测量结果进行了比较.The flux concentrator is a matching device for the positron beam, which matches the transverse emittance between the target and successive accelerator tubes. It is one of the most important parts of the BEPCⅡ positron source and for improving the positron catching efficiency. Based on the design and the manufacture of the flux concentrator, we studied the distribution of the magnetic field and the resonance property of the flux concentrator by computer simulation and compared the results with those of experiment.
