	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.

	BEPCII is designed not only for synchrotron radiation light source but also a collider. Topup operation for the synchrotron radiation facility has been realized in 2015. In order to improve the integral luminosity during the data taking of high energy physics, BEPCII began the dedicated upgrade to realize topup operation for the collider from the beginning of 2017. The modification of hardware devices have been finished at the end of 2019. The commissioning of the topup injection in the collision operation of BEPCII will be introduced in detail in this paper.
