| Abstract | The LHCb Upstream Tracker is a silicon strip tracking detector that started operation in the Run 3 of the LHC. To meet the requirements imposed by high occupancy and data rate at the HL-LHC, a new Upstream Pixel (UP) tracker is proposed for LHCb Upgrade II based on CMOS pixel sensors. A preliminary detector layout is presented. The design of a sensor in a 55 nm high-voltage CMOS technology is introduced and further development is in process. Performance studies of UP with simulation are also ongoing. |
