	The CEPC booster provides electron and positron beams to the collider at different energies. The newest booster design is consistent with the TDR higher luminosity goals for four energy modes. The emittance of booster is reduced significantly in order to match the lower emittance of collider in TDR. Both FODO structure and TME structure was studied for booster design. A lot of efforts are made to overcome the difficulty of error sensitivity for the booster and hence the dynamic aperture with errors can fulfill the requirements at all energy modes. Also, the combined magnets scheme (B+S) are proposed to minimize the cost for magnets and power supplies. The design status of CEPC booster in TDR including parameters, optics and dynamic aperture is discussed in this paper.

	Circular Electron-Positron Collider (CEPC) is a 100 km ring collider as a Higgs factory. It consists of a double ring collider, a full energy booster, a Linac and several transport lines. The Linac is a normal conducting S-band and C-band linear accelerator and provide electron and positron beam at an energy up to 30 GeV with repetition frequency of 100 Hz. After a conventional positron source, there is a 1.1 GeV damping ring to reduce the emittance of positron beam. C-band accelerating structures are adopted to accelerate electron and positron beam from 1.1 GeV to 30 GeV. For Z mode, in order to obtain higher injection speed, the Linac operates in double-bunch acceleration mode. The physics design and dynamic simulation results of the Linac will be detailed present-ed in this paper.
