Physics Shift Report¶

Start Date: 2nd July
End Date: 5th July
Start Run: 07184
End Run: 07188
Physics shifter: Francois Drielsma

Summary¶

No data was taken from the 2nd to the evening of the 4th of July because:

• The priority is placed on the magnet preparation activities.
• TOF1 was moved out of the beam line for required Tracker repairs Friday morning.

On the evening of the 4th and into the 5th, pion reference runs were taken:

• TOF1 back in the beam line
• No decay solenoid

Run number	Run type	Mom. setting	Trigger condition	Nbr. of spills	Int. part. tr.
7184	Pion +	300 MeV/c	TOF1	203	3314
7185	Pion +	300 MeV/c	TOF1	5005	80395
7186	Pion +	300 MeV/c	TOF1	3202	Missing
7187	Pion +	190 MeV/c	TOF1	1037	12878
7188	Pion +	190 MeV/c	TOF1	4741	49211

Magnet cooling status:

• Cooling SSU and SSD is "complete".
• SSU and SSD are considered suitably stable so that they may be monitored without intervention.
• The superconducting permit was be tested prior to the last shift.

Run documentation¶

Elog¶

Entries for each shift and major issues/faults. No problems found, very thorough.

Run Condition Summary Spreadsheet/CDB¶

• Integrated number of triggers missing in the spreadsheet for run 7186. Estimated TOF1 triggers: 51434 (same setting as 7185)

• Run 7184 characteristics failed to be uploaded to the CDB (~200 spills): no trigger records, no end date or end pulse, wrong target depth.

• IMPORTANT NOTE : An end note need to be written for the run statistics to be uploaded.

• Run 7185 completely in the CDB. Mismatched target depth in the CDB and the spreadsheet, no beam loss recorded.

	Nbr. of spills	Int. part. tr.	Target depth	Beam loss
Spreadsheet	5005	80395	38.15 mm	1.0 V
CDB	5005	80395	63.95 mm	/

• Run 7186-7188 not pushed to the CDB by run control.

Analysis¶

• No particular analysis requested by the measurement coordinator
• The files are on the grid

Reconstruction Quality¶

• The physics devil reports a "Download Error" for all the aforementioned runs. No plots were generated and the data were not reconstructed by it.
• The files have been properly uploaded to the grid
