To achieve the physical goals in the future circular collider, Time Projection Chamber(TPC) is one of the main concept proposal of the central tracker detector, it has an excellent performance on the moment, dE/dx and the spation resolution.
the TPC prototype with a MPGD detector module integrated the laser calibration system has been developed in Institute of High Energy Physics (IHEP). This prototype has an active readout area of 200mm$\times$200mm and the drift length of 500mm, the narrow laser beams can imitate straight ionization tracks at predefined position(<2$\mu$m). it is placed on an anti-vibration pneumatic optical platform and any vibration down to amplitudes of less than 2$\mu$m, 1280 channels readout system and the high voltage of 20,000V for the light field cage have been done, and the signal tests are very good for TPC prototype integrated 42 UV laser beams. In this talk, some performance results of dE/dx and the position resolution will be presented。
