Description
The vertex detector is a critical component of the future lepton collider, such as Circular Electron Positron Collider (CEPC). It is designed to achieve extremely high spatial resolution (3–5 micrometers) for precisely tracking the decay vertices of particles, particularly in studies related to the Higgs boson.
Significant progress has been made in the development for silicon vertex detector in China. A beam telescope device composed of six Taichu3 chips was successfully tested at DESY in December 2022, confirming that the single-point spatial resolution of the Taichu3 pixel sensor chip is better than 5 micrometers, with a detector efficiency above 99%. A vertex detector prototype featuring six double-sided ladders with 24 Taichu3 chips completed beam testing at DESY, further validating its performance.
This talk will also cover the R&D plan for the future, including prototyping a vertex detector based on stitching technology.
