N2 - The circular electron positron collider (CEPC) has been proposed to enable more thorough and precise measurements of the properties of Higgs, W, and Z bosons, as well as to search for new physics. In response to the stringent performance requirements of the vertex detector for the CEPC, a baseline vertex detector prototype was tested and characterized for the first time using a 6-GeV electron beam at DESY II Test Beam Line 21 (TB 21). The baseline vertex detector prototype is designed with a cylindrical barrel structure that contains six double-sided detector modules (ladders). Each side of the ladder includes TaichuPix-3 sensors based on monolithic active pixel sensor (MAPS) technology, a flexible printed circuit (FPC), and a carbon fiber support structure. In addition, the readout electronics and the data acquisition (DAQ) system were also examined during this beam test. The performance of the prototype was evaluated using an electron beam that passed through six ladders in a perpendicular direction. The offline data analysis indicates a spatial resolution of about 5 µm, with detection efficiency exceeding 99% and an impact parameter resolution of about 5.1 µm. These promising results from this baseline vertex detector prototype mark a significant step toward realizing the optimal vertex detector for the CEPC.
