  The CEPC injector consists of linac and booster. To meet the requirement of the booster, the linac should provide 10 GeV electron and positron beam at a repetition frequency of 100 Hz. In this paper, the overall design of the linac has introduced. For the linac one-bunch-per-pulse is adopted and bunch charge should be larger than 3 nC in the design. A 1.1 GeV damping ring with 75.4 m circumference has adopted to reduce the transverse emittance of positron beam to suitably small value.

  Considering the requirement on the dynamic aperture in the main collider, an on-axis injection method is need-ed for the Higgs energy at CEPC. A swap-out on-axis injection scheme using the booster as an accumulation ring is given in this paper. Some dynamical problems concerning the effectiveness of this injection scheme is also discussed.
