Readout electronics for the CEPC vertex detector prototype and beam telescope

Abstract

The proposed Circular Electron Positron Collider (CEPC) imposes unique requirements on the vertex detector. In response, the MOST1 and MOST2 projects were launched with the aim of developing a fully functional pixel sensor and implementing the prototype of the inner tracking detector. To efficiently manage the data flow from multiple sensors, specialized readout electronics are required. In order to evaluate the MOST2 project indicators set for the vertex detector prototype, a beam telescope was constructed using six TaichuPix-3 sensor chips and applied in different experiments. The experimental results demonstrate that the telescope functions effectively and that the detector prototype meets the design objectives of the MOST2 project. This project encompasses the design of the readout electronics, the functionality of the readout system, the architecture of the telescope, and the specifics of the telescope experiments.
