January 2009 offline detector review - 2 nd go 1 ● Offline – Geometry – Material budget – Simulation – Raw data – OCDB parameters – Reconstruction ● Calibration Issues – Online Calibration – Offline Calibration – GRP – Trigger – Questions for CORE (new!)

Geometry 2 ● Are any changes in the geometry and material descriptions expected/foreseen? – Maybe. Currently FMD2+3 are off by ~4mm away from IP, possibly due to incorrect SPD geometry. ● Is the current situation satisfactory? – Yeeees, but we'd prefer to move back to design. ● Full/survey misalignment: is it possible to introduce full or survey misalignment without creating overlaps? – Internally yes, but the survey story is a bit muddy. More on this on a later slide!

Material Budget 3 ● Is the current step size good for the calculation of material budget and for energy loss correction? – Not investigated at this time. Off-hand the step size seems fine.

Simulation - Time 4 ● Is step manager correctly storing the time of the hits – Yes! ● Does the digitization take into account the time of the hits – Yes! ● Does the digitization simulates correctly the time response of the readout (binning, time windows etc.) – Yes! Time information in simulation (needed for pileup sim and more realistic detector response - this item is new, we never asked them before!)

Simulation – Other (1) 5 ● Is the memory and CPU consumption under control at each simulation step: hits, sdigits, digits? – Yes ● Labels: are the labels from the kinematics tree correctly propagated to hits, sdigits, digits? – AliFMDBaseDigit (AliFMDDigit and AliFMDSDigit by extension) inherits from AliDigit. – Up to 3 track labels stored. Warnings in case of more needed. – SVN revision 30718

Simulation – Other (2) 6 ● Track references: are the track references needed and if yes, are they correctly implemented in the step manager? – Needed for BG correction. Implemented. Needs a little bit of testing. ● Event merging: is the event merging correctly working for the detector? – Not tested at this time. – Cvetan will setup test-bench soon ● Embedding: is the track embedding foreseen in your detector? If yes, is it working correctly? – No. – AliFMD::Raw2SDigits implemented and working – SVN revision 30718

Raw Data 7 ● Is the raw data format already fixed, or additional changes are needed? – The raw format (ALTRO format) has recently undergone some transformations. The responsibility for making proper decoders/encoders lies with a working group steered by Luciano Musa. Cvetan will most likely do the final implementation.

OCDB parameters : simulation vs reconstruction 8 ● Are the gains stored in OCDB correctly used both in the simulation and reconstruction? – Yes. Also applies to pedestals, conditions, and other such parameters. ● LHC machine parameters to go to GRP – Currently not used. – Could use: Beam energy, and type.

Reconstruction (1) 9 ● Are all the necessary reco params in OCDB (including params for cosmic reco) – Yes (none needed) ● Are reco params fully used in the reco – No, since none are needed :-)

Reconstruction - Track reconstruction (2) 10 ● Shift in the reconstructed Pt: is the problem understood ans is the current situation satisfactory? – N/A ● Doubly found tracks: is the reported increase confirmed and is the origin understood? – N/A ● Is the propagation status correctly taken into account? If the propagation fails, are the track parameters left unchanged? – N/A

Reconstruction – V0 reconstruction (3) 11 ● Low V0 efficiency if the propagation failed – N/A ● Like sign V0s requested for background studies – N/A ● Shift in the reconstructed radial coordinate of the gamma conversion points – N/A

Reconstruction – PID (4) 12 ● Eta dependency of PID efficiency: is it understood? – N/A ● PID efficiency at the relativistic rise: is the comparison data vs MC OK? Is the results understood? – N/A

Online Calibrations 13 ● Status of the procedures (DAs, preprocessor) – All 3 done, tested, and working ● Status of the DPs definition (new DPs foreseen, status of their implementation) – Done – none needed. ● Run types defined for your preprocessor (are they correctly implemented in ECS / treated in your preprocessor?) – Yes. ● Status of the calibration objects (new objects needed?) – Done

Offline Calibration 14 ● Status of the procedures after the Offline October '08 Week – First step procedures done. Second step procedures (Sharing, BG and acceptance corrections, and multiplicity cuts) well underway. ● Status of the calibration objects (new objects needed?) – No new first step procedure objects. Second step storage of objects generally not settled in AliROOT yet. Latchezar has more information.

GRP 15 ● Information you may need to have added in the GRP preprocessor – We could want collision system, and energy. ● Run types for which you may need the GRP to run – All run types (since needed for offline passes): ● Physics ● Standalone ● Pedestal ● Gain

Trigger Information - in case your subdetector is a triggering detector 16 ● Information you may need to retrieve – N/A ● Procedures you may need to apply – N/A ● System (DAQ/DCS/HLT) you may need to interact with to retrieve your information – N/A

Questions for CORE 17 ● Disparately need large (~10M events) pp sim for Background studies – when is this planned? ● Can we skip Digit and RecPoint creation in AliFMDReconstruction? ● Plans for external data in Analysis – any estimate on this?

More on geometry (1) 18 ● Avoid overlaps between FMD2 and 3 support and SPD thermal cones – Δ z ~ +4mm for FMD2 (away from IP) relative to design – Δ z ~ -4mm for FMD3 (away from IP) relative to design ● Survey of FMD2 gives Δ z ~ +1±1mm relative to design. ● Survey of ITS gives Δ z ~ +2.9±1mm – SPD and FMD survey says: Overlap of 6mm on FMD2 side! 1Mm overlap on FMD3 side.

More on geometry (2) 19 ● Accurate drawings of FMD2 and 3 used. ● Only simple drawing of SPD thermal screen used. – Δ z ~ +4mm for FMD2 (away from IP) relative to design – Δ z ~ -4mm for FMD3 (away from IP) relative to design

More on geometry (3) 20 ~9mm gap
