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.

ASAP tested on many different datasets:• H8 2002, 2003, 2004 • Cosmics rays in sector 13• Toroid mechanical release • Toroid B field on• Sector 05

Input: AMDB, calibrations, current optical data, muon track parameters, surveys etc. etc.

Output: A-lines (x,y,z,tx,ty,tz of each MDT chamber, in the local chamber coordinate frame) B-lines (8 deformation parameters for each MDT chamber)

Todo list: • Enter and understand all calibration data in view of absolute alignment.• Speed up the fitting procedure (sparse matrix, maybe fragmentation)• Implement fit using High Pt tracks (Pseudo Track Sensors)• Implement fits using straight tracks• PVSS visualization of fit results

Todo list:• Interface to PVSS• Interface to Oracle (following Barrel implementation)• combined (track+optic) alignment reconstruction (tested prototype exist so far)• check coordinate system compliance with GeoModel/AMDB

Database

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:

1. Fit information (quality, number of used/defect sensors, time etc.)2. A lines containing (x,y,z,tx,ty,tz)3. B lines containing the MDT deformations (8 parameters)4. (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.

Application Server


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….)

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…

Full chain had been tested in H8-2004 (at least for MuonBoy)

Today part from Oracle to TSD implementedby 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)

=> In parallel (or together) with R-T calibration stream, a track alignment stream has to be setup.

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:1. Small versus Large Barrel towers2. BIS8 versus BIS73. BEE versus EndCap4. EndCap versus Barrel5. Inner tracker versus muon spectrometer

For all these dataflows, data have to be Processed at the Munich Tier2.

The alignment fits can be done at CERN.

ID versus Muon, quite similar dataflowWork just started by Tony Liss.MPI will adresse it soon.


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 HzRT Calib stream : 700 HzAlignment 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.

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

Initial geometry


Manpower today

Barrel optical alignment software: Florian Bauer, Pierre Francois Giraud, Egge van der Poel

Barrel alignment acquisition: Robert Hart

EndCap optical alignment software: Christoph Amelung

EndCap alignment acquisition: Kevan Hashemi, Joe Rothberg

High Pt Track alignment: Serguei Kotov, Jens Schmaller

Inner Tracker versus Muon spectrometer:

Tony Liss

Tier2 Alignment + RT responsable Oliver Kortner

Initial Geometry using straight tracks: Henry Bachacou, Clement Helsen, Eric Lancon

Database issues: Andrea Formica, Joe Rothberg, Monica Verducci

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

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
