CEPC Silicon Tracker Detector

The Circular Electron-Positron Collider (CEPC) is designed to explore the properties of the Higgs boson and search for new physics beyond the Standard Model. The CEPC silicon tracker, with a total active area of about 100 m2, is optimized to measure charged particle tracks over a wide momentum range, from below 1 GeV/c to above 100 GeV/c, for precision measurements of high-momentum isolated tracks and accurate reconstruction of low momentum tracks in dense jets. The required momentum resolution reaches the level of one per mille. The silicon tracker system integrates advanced pixel and microstrip sensors, readout electronics, and mechanical and cooling structures. This report presents the overall design of the reference detector.
