Online analysis: results and TODO

Back to DVCS

This page is in progress, please new items to it. When you obtain a result, log in into the Halog and link it to this page. if you are willing to take charge of a given analysis, please indicate it on this page as well as the date at which you are starting to work on it.

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 (Florian Itard is keeping up with that)
• Start a database of run indicating line by line the run number, the target in position, the average beam current, LHRs pnom, LHRS angle, the purpose of the run

Luminosity, efficiency

Boiling test

These data do not exist yet, waiting for BCM calibrations to happen

• Establish history of the data taking against the boiling test
• 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 and also data taken around 10-14. Asked Malek if he wants to do that on 10-14. Online analysis by B. Michaels [here]

LHRS commissioning

Calibrate the ADCs:

Still to be done S1, Pion rejector,

[Cerenkov], [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/sieve)

Ye Zhihong is interested in this analysis and started it.

BPM calibration

• [Initial calibration]

BCM calibration

• the initial calibration was done on 10-14. It needs to be analyzed. [halog]
