1. Status of the Software and MC production Antoine Cazes Laboratoire de L’accélérateur Linéaire

2. OPERA collaboration meeting - 5th of june 2004 Antoine Cazes Analysis The Software chain Beam Files OpRoot OpRec OpTreeConvert Simulation Files Reconstructed Files OpDigit OpSym: OpGeom, OpVMC Available for the summer Used for the present MC production OpNtuple MyAna

3. OPERA collaboration meeting - 5th of june 2004 Antoine Cazes Software Status OpROOT(D.Duchesneau) Test have been performed Problem for neutral charmed particle fixed Few improvements OpDigit No Changes OpRec(AC, JEC) Pattern : No Changes Tracking: Tentative of including the tracking in the spectrometer. But it is not working Old version is used : use MC information for initialization of the track ending in a Spectrometer

4. OPERA collaboration meeting - 5th of june 2004 Antoine Cazes Tracking in the spectrometer: Tracking in the Spectrometer: Kalman filtering parabolic include matter effect. include magnetic field It has been coded. X-Y reconstruction Slope reconstruction Momentum reconstruction OK Diverge!!!

5. OPERA collaboration meeting - 5th of june 2004 Antoine Cazes Temporary Solution Use of the old Kalman filtering Tracking in the Target Tracker. Kalman filtering including matter effect initialization with fit on the first points Track going through the spectrometer initialization using MC information Tracking done only in the first hit TT Already more realistic, since pattern do not use any MC information.

8. OPERA collaboration meeting - 5th of june 2004 Antoine Cazes OpNtuple (A.Marotta) OpNtuple is a converter from the official output of the software chain to Hbook files It is available on cvs (v2) Derived from MyAna For compatibility reason, the information stored are (almost) the same as in the previous Ntuple production (may 2001)

14. Monte Carlo Production

15. OPERA collaboration meeting - 5th of june 2004 Antoine Cazes Production Status December 2003 production was not perfect We started a new production (may 2004) Input Beam Files from may2001 Vertices only in lead. Tracking is included. Already 10,000 or 5,000 events of type:  CC  NC Tests are under going to check the quality.  ntuple is investigated Full production as soon as checks are OK  e  e QE   QE

16. OPERA collaboration meeting - 5th of june 2004 Antoine Cazes File location: Files are stored on the CASTOR area: /castor/cern.ch/opera/mc/prodmay2004/ simul/ : ouput of the simulation digit/ : output of the digitization reco/ : output of the Reconstruction: ntuple/ : output of the Hbook converter  File name structure : numucc1_reco_1.root Type of event Beam file number (1-3) Level in the chain (simul, digit, reco) Simulation file number (1-6 for one Beam File)

17. OPERA collaboration meeting - 5th of june 2004 Antoine Cazes Crash problem OpRec and OpNtuple experience crashes for big files when running in batch. Apparently, there is a memory problem, in the OpIO package, maybe memory leak Test using dedicated debuging software are foreseen. Purify Insure Does not stop the production (just slow down ) Temporary solution: number of event/file limited to less than 3000.
