Present: E. Fuchey, C. Hyde, C. Munoz-Camacho, J. Roche
- Starting next week we will meet on Monday at 9:15
- Tanja Horn has approched Carlos and Charles to discuss possibilities of running DVCS in Hall C. The idea would be to put together a compelling program of exclusive (and semi-inclusive ?) reactions including pi0 production and DVCS. The idea was prompted by the recent disappointing PAC results concerning pi0 studies. The current idea is to have Tanja join us at the DVCS collaboration meeting in Orsay (Nov 12-13, 2012). Discussions are on-going.
- Carlos reports that the waveform analysis of the calo data was completed. The data are beeing transfered to JLab. Carlos expect the files will all be at JLab by next Monday. Malek will perform timing correction. After that the ntuples will be created.
- Angle calculation. Malek and Carlos found the bug in the comparison of the angle of proton elastically scattered calculated (based on beam energy and measured momentum) and measured in the LHRS. Now that the bug has been fixed, a ~ 1mr systematic error remains. Charles states that this is the type of mispointing ususally obtained with the HRS, Carlos wonders why the mismatch is systematic instead of random. Now that this issue is fixed, Carlos reminds us that the original question was the actual location of the calorimeter. Elastic data revealed a 0 to 6 mm lateral displacement of the calorimeter. The deplacement amplitude depends on kinematic and even on the day of the data taking. The HRS check was just to rule out a HRS mis-pointing. The question remains where is the calo?
- Eric just posted a new version of the pi0 results: clearer figure, new text that is hopefully clearer and that doesn't introduce new notation. Goal is to put in the archive soon. We wil discuss this during next week meeting.
- DVCS3 (12 GeV schedule) Al Gavalia and Thia had a meeting last week. Unfortunately Charles could not attend. From what we know the parallel running with GMP is stillbeing discussed.
