摘要
The Hefei light source(HLS) has been upgraded into HLS II, with increased brightness and stability. In this paper, the new injection system is described. Elegant program is used to simulate the particles motion in 6D phase space. In the process of tracking simulation of electrons, the system tolerances and magnet errors are introduced. Influences to the injection efficiency from beam injection deviation are studied. These provide important reference for realizing the Top-up injection.
