Description
The TaichuPix series chips, as sensors designed for the CEPC vertex detector, do not have a complete digital model, resulting in lower accuracy in simulations, especially in the long barrel's forward region. Allpix-Square, as an open-source software, is able to simulate the physical process of silicon pixel detectors and digitization of the front-end electronics. With the beam test results with different incident angles at BRSF we conducted, and the AllPix-Squared simulation, we will be able to achieve high-precision digitization for the TaichuPix-3 chip. This report will show the comparison between simulation and beam test results in cluster size and efficieny variation with the incident angle and threshold.
