Abstract：
In TOF measurement, the factors that can increase the time resolution include noise, amplitude measurement error, and the difference of pulse amplitudes and shapes. This article discusses how these factors affect time resolution, and performs quantitative analysis based on the GEANT4 simulation result of the BESⅢ's TOF detector. The result shows that the discriminator level must be selected carefully. To get better time resolution, pulse waveform digitizing is necessary.
