Description

The project aims to develop AC-LGAD based strip silicon sensors and detector modules for the outer tracker in future lepton colliders (CEPC, FCC-ee, ILC, CLIC, etc.). This development is crucial for enhancing the flavor physics and Higgs physics potential of these future lepton colliders.

The primary objective is to develop AC-LGAD sensors with a long strip structure. Additionally, we plan to create AC-LGAD strip sensors for the endcap region, where the strips will be oriented along the azimuthal direction. The developed sensor prototypes, along with ASICs featuring high-precision TDCs, will be used to construct detector module prototypes. These modules are expected to achieve a spatial resolution better than 10 μm (R-phi direction) and a timing resolution in the range of 30-50 ps. We anticipate that this development will significantly contribute to the technical design reports for future lepton collider projects.
Collaborative work with WG5-TB is foreseen, with potential synergies in the timing tracker development for the EIC.
