BESIII barrel time-of-flight (TOF) calibration using cosmic ray data

O4; The principle of the method for the BESⅢ TOF calibration using cosmic ray data without magnetic field are reported in this paper.After applying calibration constants,the single-end readout time resolution could reach about 150 ps,and the time resolution for one layer is achieved to be about 110...

Description
Summary:O4; The principle of the method for the BESⅢ TOF calibration using cosmic ray data without magnetic field are reported in this paper.After applying calibration constants,the single-end readout time resolution could reach about 150 ps,and the time resolution for one layer is achieved to be about 110 ps.The paper also described the extraction scheme for the event start time of cosmic events.
