Abstract：
BESⅡ detector has been upgraded from 1995, the TOF time resolution is about 180ps for Bhabha events, a big improvement compared with 330ps of BESⅠ. With the upgrade of the detector, the software including calibration, reconstruction and Monte Carlo (M.C.) simulation needs corresponding improvement, especially for M.C. simulation. Using 50M J/ψ data taken in the last two years at BESⅡ, we studied the TOF resolution carefully, and made some improvements for TOF MC simulation. After such an improvement, we compared the TOF resolutions between real data and M.C. data and found they agree with each other.
