本文讨论了偏转磁铁和磁四极透镜对的成象条件,并给出一些不同参数的偏转磁铁和磁四极透镜对的成象曲线。我们曾对离子光学系统的设计问题进行了一些调研,对离子光学系统上常用的元件,如偏转磁铁、磁四极透镜的性能,进行了一些计算,积累了一些数据资料。现将这些数据整理出来,供有关的同志参考。 This article discusses the imaging conditions of a deflecting magnet and a magnetic quadrupole lens pair and gives some imaging parameters of deflection magnets and magnetic quadrupole pairs with different parameters. We have done some research on the design of ion optical system. Some calculations have been made on the performance of commonly used components in ion optical systems, such as deflection magnets and magnetic quadrupole lenses. Some data have been accumulated. Now these data are sorted out for reference by the relevant comrades.
