摘　　要：Purpose A compact T0 detector with high time resolution is developed.Methods The T0 detector is based on a multi-anode MCP-PMT coupled with two fused quartzes.The characteristics of this MCP-PMT are studied by a fast laser pulse in laboratory firstly.Cosmic ray test has been carried out to study T0 detector's signal features and time resolution.Conclusions by off-line analysis The T0 detector's time resolution is less than 40 ps for the cosmic ray events.It can be applicable in cosmic ray test,beam test,collider experiment and detector developments.
