Matching data taking with run plans

• Update the how to
• Maintain db_run.dat file: Make sure that every LHRS momentum and angle changes are logged
• Establish history of the data taking against the optics run plan. Add run numbers to each step of the plan
• Establish history of the data taking against the boiling test
• Start a database of run indicating line by line the run number, the target in position, the average beam current, LHRs pnom, LHRS angle, goal

Luminosity, efficiency

• Boiling test:

Still to be done : Analyze data of the boiling test, conclude

• Trigger efficiency

Analyze data taken on the week-end of 10-09 and 10-10 with T3 and T4 trigger

LHRS commissioning

• Calibrate the ADCs:

Still to be done S1, Pion rejector,

[Cerenkov (partially done, missing cer1, 10-09)], [S2 (done 10-09)]

• Calibrate detector time spectra:

Still to be done : understand timing spectra for S1,S2 and the Cerenkov

[t0 for VDC (done 10-09)]

• LHRS optics run no sieve
• LHRS optics run sieve
