  4. Barrel RasDim DAQ Athena M-Programs Today all installed MDT are cabled. 10 PCs installed in USA15 using RasDim (under PVSS). DAQ runs smoothly. No major problems today. Data are stored into Oracle database tables. Next step: integration into general ATLAS DAQ frame using PVSS. Readout: 1st step: 5627 lines are read in parallel (740sec). 2nd step: 206 mixed line are read using control PC (200sec) Total readout time: 16 minutes.

  9. Database Athena M-Programs • INPUT • Storage of Temperature data: • char name, int time, double T • Storage of Barrel optical sensor data: • char name, int time, int error_code, double x,double y, double mag, double tz • Storage of EndCap optical sensors data: • int stime, int image_id, int file_id, double x, double y, int number_of_pixel • and other diagnostic tools…. • OUTPUT: • 4 tables are written: • Fit information (quality, number of used/defect sensors, time etc.) • A lines containing (x,y,z,tx,ty,tz) • B lines containing the MDT deformations (8 parameters) • (x,y,z,tx,ty,tz) in ATLAS coordinates of all the B-sensors. Used for B-field calculation. • First 3 tables have to appear under ATHENA and are converted into COOL format. • For the Barrel all this works today, EndCap will follow very soon… • Over the last 4 month the Oracle database turned out to be very reliable! • Great Job done by the IT group.

  10. Application Server Athena M-Programs Geometry Survey Calibration LWDAQ Condition Database ARAMyS Temp ASAP AMDB Survey Calibration RasDim ApplicationServer: 1) retrieve data from MySql/Oracle/Ascii 2) launch IntervalMaker 3) launch ASAP 4) write ASAP output data in MySql/Oracle/Ascii 5) later on Application Server will write ASAP data into Cool Application server uses Hibernate library. Hibernate is an interface to all type of database (it is based on JDBC, Java equivalent of ODBC) Application server is meant to be triggered by RasDim, via a DIM server. All this has been developed by Andrea & Pierre-Francois. Nice tool to control and launch ASAP from any place via internet browser…. (f.e. from an internet café in the Bahamas….) JDB-Plot ApplicationServer Florian Bauer, SVSG, 05/03/2007

  11. JDB-Plot Athena M-Programs • Other example of ApplicationServer: • Java database browser. • Retrieve data from MySql/Oracle tables and • convert them automatically into ROOTtree, Ascii Files • Selection criteria possible • possibility to plug ROOT macros • No a priori knowledge on the table structure needed • (provided no pointer to funny structures/objects are stored in the tables) • Even nicer tool to check last night runs from an internet café in the Bahamas… Geometry Survey Calibration LWDAQ Condition Database AraMys Temp ASAP AMDB Survey Calibration RasDim JDB-Plot ApplicationServer Browser Plugged macro Florian Bauer, SVSG, 05/03/2007

  12. Athena implementation Athena M-Programs Geometry Survey Calibration Full chain had been tested in H8-2004 (at least for MuonBoy) Today part from Oracle to TSD implemented by Monica Verducci and Andrea Formica. Automatisation is planned. For Barrel A-lines, coordinate system convention is the same between ASAP-AMDB-GeoModell B-lines are not implemented in GeoModell, probably they will pass via the RT-service (which should handle wire sag, RT and deformations) LWDAQ Condition Database ARAMyS Temp ASAP AMDB Survey Calibration RasDim JDB-Plot ApplicationServer IntervallMaker The adventures of the A&B-lines: Today done manually ASAP AraMys COOL Oracle table BLOB Ascii file Transient Data Store Geomodel RT Calib Service MuonBoy Moore MuonGirl MoMu Florian Bauer, SVSG, 05/03/2007

  13. High Pt track alignment (1) • During data-taking: optical alignment does not cover all the muon spectrometer. • High Pt tracks (pt>20GeV) have to be used • Combination of high pt track information with optical ones. • 5 cases: • Small versus Large Barrel towers • BIS8 versus BIS7 • BEE versus EndCap • EndCap versus Barrel • Inner tracker versus muon spectrometer Requirements 30 mm precision on Pt measurement 200mm precision in the toroid bending plane => In parallel (or together) with R-T calibration stream, a track alignment stream has to be setup. Florian Bauer, SVSG, 5/3/2007

  14. Some High Pt track alignment examples (2) Small versus Large MDT EndCap versus Barrel BIL EIL RPC EES BOS BOL EEL BML BOL BML BMS Trigger zone for overlapping tracks BIL MDT overlap BIS Florian Bauer, SVSG, 05/02/2007

  15. Tier2 ATHENA Segments reconstruction In BIS7 and BIS8 Fit of BIS8 position w.r.t. BIS7 Segments in BIS7 and BIS8 A-Lines BIS8 Overlap Track digits A-Lines BIS7 High Pt track alignment (3) Tier2 ATHENA Track reconstruction in the large chambers + Segments in the small chambers Segments in the small chambers: Predicted from large Reconstructed in small Overlap Track digits ASAP optic ASAP combined A-Lines optic A-Lines combined BEE chambers Small/Large Tier2 ATHENA Track reconstruction in EIS-EMS-EOS + BEE Segments Segments in BEE Predicted from EI-EM-EO For all these dataflows, data have to be Processed at the Munich Tier2. The alignment fits can be done at CERN. Overlap Track digits ARAMyS optic Segment Fit A-Lines optic A-Lines BEE BIS8 chambers EndCap versus Barrel Tier2 ATHENA Track reconstruction in the Barrel + Segments in EIL4 Segments in EIL4 Predicted from Barrel Reconstructed from digits ID versus Muon, quite similar dataflow Work just started by Tony Liss. MPI will adresse it soon. Overlap Track digits ASAP optic Global fit combined A-Lines optic A-Lines combined ARAMys optic Florian Bauer, SVSG, 5/3/2007

  16. High Pt track alignment (4) Quasi-online alignment. These alignment correction should be available within 24 hours. For the track reconstruction, need of a Tier2. Location: Munich with 20 CPUs allocated for this task. Muon trigger rate LVL2: 2500 Hz RT Calib stream : 700 Hz Alignment stream : 200 Hz (all 1+1 overlaps) Work plan for Munich calibration center: March: local stream -> processing -> Oracle DB April: stream coming from CERN -> processing -> Oracle DB at CERN Trigger for these overlaps, defined but not implemented today. Should come with release 13. Today only test possibilities: CDC Monte-Carlo. Work started on small/large (200 000 tracks with 20 GeV). See talks of Serguei Kotov and Jens Schmaller last muon week. Refresh rate: 2 hours Refresh rate: 6 hours Florian Bauer, SVSG, 5/3/2007

  17. Initial geometry 3 possibilities to determine initial geometry: - geometer surveys - straight muon tracks coming from: - cosmics, - beam halo - toroid off, solenoid on, straight tracks - absolute alignment a) Geometer surveys: EndCap wheels: many targets sighted (almost 4 per chamber) Barrel limited to very few chambers on the outside ( most of them not in final position + survey performed at various toroid loads…) b) Cosmics: Beginning March 2007: Each Barrel sector will undergo cosmic run. One sector per month. First studies & results available for sector 13… Otherwise CDC simulation asked to test the algorithms. c) Beam Halo: Probably End 2007. d) Toroid off, solenoid on: Data with first collisions at 14TeV(~several days). CDC Simulation asked for All these 4 ingredients can be put in a common fit. The initial geometry resulting from the track fit, can then be compared to absolute alignment. Considered to be a “one time task”. The amount of work here is by no means negligeable.. Work started for sector 13. Florian Bauer, SVSG, 5/3/2007

  18. Manpower today • Most people in this list are part-time • Border between commissioning and software very permeable… • e.g. FB/PFG/CA mostly (80%) occupied with installation in the pit • CA CERN contract finished end 2007 • EvdP, JS and CH are involved 30-50% of their time and for short period Florian Bauer, SVSG, 05/03/2007

  19. Conclusions • Optical alignment DAQ are on a good way • Alignment reconstruction programm (ASAP & ARAMyS) are well advanced • ATHENA implementation should not cause major problems. • High Pt track alignment is the next biggest software challenge • Initial geometry using straight tracks just started. • Absolutely important for muon spectrometer understanding. • Manpower is sub critical in many domains: • Track alignment (using CDC and cosmic data) • ASAP development eaten up by installation • ARAMyS 2008-2010 not guaranteed Florian Bauer, SVSG, 05/03/2007
