Summary¶
23/02: First day of data taking was divided in several activities
- Beam bump tuning with H.N. and D. Adams in the morning
- Shifter training from 2PM to 3:30PM
- TOF calibration data taking until 10PM (no DS, data looks fine from onRec), reached 500k TOF1 trig.

24/02: Second day of data taking
- FC being bolted to the SSs, evacuation of the absorber cavity (all day)
- /!\ No reference run taken !
- Resume data taking operations, alignment data, reached 550k out of 1M

25/02: Third day of data taking
- Work in the hall during the day to evacuate the FC cavity
- Resume alignment data taking at 7PM, reached 750k integrated total particle triggers for the first setting, 23k for the second setting.
- /!\ Proton absorber too thin for all the runs that day (29 mm instead of 82 mm), must be set manually. Might be some proton contamination in the beam up to TOF1 at most (5 cm of PVT in TOF0).

- Work in the hall during the day for the FC and setting up the DS power supply
- Resume alignment data taking at 4PM, reach 50k for the second setting (very poor rate without DS), 150k for the third setting.

Run documentation¶
Elog¶
- Entries for each shift and major issues/faults. No problems found, very thorough.
- Check list filled on a regular basis, good practice
Run Condition Summary Spreadsheet/CDB¶
- All of the information recorded in the Summary Spreasheet
- Run 7621 (calibration run) missing in the CDB
Analysis¶
- No particular analysis requested by the measurement coordinator
- The alignment analysis needs a resurvey of the downstream PID detector to take place.
- Amount of statistics collected for the TOF calibration from the 7623-7625:



Reconstruction Quality¶
- The physics devil processed the files successfully and reported a reasonable number of unpacking errors (< 0.1%)
- The files have been properly uploaded to the grid
- The on line reconstruction plots don't reveal any DAQ issues, albeit a noticeable inefficiency in tracker 1 station 1. Might be solved by updating the cabling file, TBD.
