	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.
