摘　　要：The beam halo is a major issue for interaction region （IR） backgrounds at many colliders, for example, future linear colliders, B factories, and also it is an important problem at ATF2. In this paper, we report on the halo propagation along the ATF2 beam line with realistic apertures, the nonlinear optics influence on the increasing number of halo particles input is analyzed, and the transmitted halo particles distribution just before the last BPM is then described, the results from which will benefit the Compton recoil electrons measurement.The beam halo is a major issue for interaction region （IR） backgrounds at many colliders, for example, future linear colliders, B factories, and also it is an important problem at ATF2.
