Description
To meet the high precision physical goals in the future e$^+$e$^−$ circular collider (CEPC), the high resolution tracker detector for the particle track reconstruction ($\lt$100$\mu$m) and particle identification are demanded. Time Projection Chamber (TPC) is one of the main concept option of the central tracker detector. the status and update R&D results of TPC module and prototype for the specific requirements will be presented in this talk. TPC module will could suppress the ions in chamber continuously running in the different gains (2000-5000) and T2K mixture gases, and TPC prototype with MPGD detector module integrated the narrow laser calibration tracks system. This prototype has an active readout area of 200$~$mm$\times$200$~$mm and the drift length of 500$~$mm, the narrow laser beams can imitate straight ionization tracks at predefined position. 1280 channels of the electrics readout and the 20,000V of the field cage have been commissioned. Finally, the update results of the simulation and consideration will be given using the pad and pixel TPC detector concepts operating at the high luminosity $Z$ pole at CEPC.
