The Technical Design Report (TDR) for the Circular Electron Positron Collider (CEPC) accelerator, designed as a Higgs and high-luminosity Z factory, was released in 2023. The baseline detector concept includes a large 3D tracking system, featuring a high-precision Time Projection Chamber (TPC) as one of the main tracking detectors, embedded in a 3.0T solenoid field. This design is also...

Particle identification (PID) is crucial for the CEPC physics, with a promising breakthrough involving cluster counting. This method quantifies primary ionizations along a particle’s trajectory in the gaseous tracker (DC/TPC), moving beyond traditional dE/dx measurements. However, a significant challenge in cluster counting is the development of an efficient reconstruction algorithm to...

A low-power front-end ASIC, named WASA, has been developed for the CEPC Time Projection Chamber (TPC). Power consumption is a critical concern and has been addressed by utilizing a 65 nm CMOS process and a circuit structure with simple analog circuits. Three prototype ASIC chips have been designed and fabricated: a 5-channel analog front-end (AFE) chip, a SAR ADC chip, and a mixed-signal chip...

Future circular electron-positron collider has been proposed as both Higgs factories and high-luminosity Z factories. The conceptual design of the updated detector includes a tracking system, with the Time Projection Chamber (TPC) serving as the primary tracking detector. The TPC offers high spatial resolution (approximately 100 µm over the entire drift length in a 3T magnetic field) in a...
