1. Recent Result of TOF Monitor System Qian LIU

2. Outline  Ref-PMT  Barrel TOF  End cap TOF

3. Ref-PMT

4. Barrel Single TOF

5. Barrel TOF Q

6. Barrel TOF Q mean

7. Barrel TOF T

8. Barrel TOF T sigma

9. Barrel TOF T sigma after Q-T

10.  The two dead east TOF counters have been fixed.  Q mean is lower: BIW36 (808), BIW48 (603), BIW49 (761), BIW83 (952), BOE66 (879)  Q mean is higher: BIW6(2520), BOW7(2604)  T sigma is higher: BOE66(35)

11. End cap single one

12. End cap Q Total 4 dead Channels! Pre-amp?

13. End cap Q mean

14. End cap T

15. End cap T sigma

16. End cap T sigma after Q-T

17. Discussion  Tuning the End cap HV.  Regular run (including in the BESIII calibration run?)  Temperate data base access.  HV data base access.

18. Thanks!
