Based on GEANT4, the authors have systematically simulated the time detector in Radioactive Ion Beam Line in Lanzhou (RIBLL). The photon total collection efficiency, photon collection efficiency and time resolution under 3 cases arriving at photocathode, following the incident particles at different position, were obtained. The main factors, which can affect the detector's performance, were given and some improve schemes were proposed.
