摘要：介绍了ＨＩＲＦＬ切束线的束流动力学设计思想。在此设计中，ＨＩＲＦＬ剥离器后被废弃的多余电荷态束流被一特殊的切割磁铁从主束运线上切割出来，经过一定的动力学制备，有效地传送到一个小实验区，为同时使用ＨＩＲＦＬ的ＳＳＣ中能束流和ＳＦＣ低能束流进行两种物理实验提供了可能性。此设计为切束线工程建设提供了确切的理论依据。

摘要：The atomic phyiscs experimental platform was desigend based on a high performance ECR ion source and is taking the responsibility for series of experimental research concerning multiple charge state ion beams, such as atomic and material phyiscs research, study on ECR ion source and working mechanism as well as the responsibility to provide reliable experimental data of required ion beams for HIRFL accelera-
