Supervisor: JH Lee, with:
Log book#8 pages 1161 - 121
Shift Summary:
------------------------------------------------------------
1. Machine:
- Beam is cogged since 21:30
- ZDC rate: 100/sec and
- Event rate: 50/sec with triggers 1,3,4,8
at the beginning of the store
- Vertex centered at ~ 0 with sigma ~ 45cm
2. Data
- TDC Calibration runs: runs 4709 and 4710
(run 4710 is for testing time dependence of TDC's)
- Physics Data: Run 4711 (~200K trigger 1 events so far)
- MRS at 90 (2B) and FS at 8 degree (A)
3. Achivements
- Fixed TOFW Mapping Error for Channels 51-55 (FV)
- Changed Fiber HV settings for better signals (DB)
4. Problems
- No new detector/HV problem except
a few minor/known ones
(TOFW 56 Top, TOFW 18 Bottom, H1 33 Bottom,
few missing channels in DC's...)
