A physical design study of the Circular Electron-Positron Collider (CEPC) booster is reported.The booster provides 120 GeV electron and positron beams for the CEPC collider with top-up injection.The booster is mounted above the collider in the same tunnel.To save cost,the energy of the linac injector for the booster is chosen as 6 GeV,corresponding to a magnetic field of 30.7 Gs.In this paper,the booster lattice is described and optimization of the cell length is discussed.A novel scheme of bypass near the detector of the collider is designed.The extremely low magnetic field caused by low injection energy is studied,and a new ideal of wiggling bands is proposed to mitigate the low-field problem.Beam transfer and injection from the linac to the booster are considered.
