Description

The AC-LGAD technology is chosen to be used as the time of flight detector and out track for the Circular electron-positron collider (CEPC). As suggested by the CEPC board, the time of flight is urgent for the flavor physics in CEPC, especially for the $K$/$p$ and $K$/$\pi$ separation in the low-energy part. The AC-LGAD based ToF & out tracker would be located between the TPC and ECAL which would cover 90 m$^{2}$ area. The expected performance is the 50 ps time resolution and 10 $\mu$m spatial resolution. This study will show the current test results with the strip AC-LGADs. The time resolution is ~37 ps and the spatial resolution is ~8.5 $\mu$m.
