Tracker Recon Report
Ground Software Meeting
August 12, 2004
 

• Alignment
  • Alignment algorithm now running in Gaudi framework
    • Not fully operational, needs complete testing (especially rotations)
  • Application of alignment constants in reconstruction is in debug stage.
  • Will soon be able to do the full circle test:
    • Generate events with a misaligned tower
    • Run the alignment algorithm to generate alignment constants
    • Apply these constants in the reconstruction to recover "perfect" geometry
       
• Re-structuring TkrRecon
  • Two active efforts directly on restructuring TkrRecon:
    • Redesign of Track Fit TDS class
      • First draft of TkrTrack, containing TkrTrackHit and TkrTrackParams classes done
        • Not yet "perfect" but good enough to get to the next problems
        • Believed to remove all problems previous classes created for converters
        • Now purely data containers, no calculations allowed!
          • Separate classes for use in recon (containing "math" operations)
          • "Helper" classes to extract detailed information?
      • Working to convert the "generic" track fit to use the above as a first test
        • Ok, will also modify display so results can be seen
    • Redesign of cluster class
  • One additional effort:
    • Developing TkrRecon "event shape analysis"
      • Runs on TkrClusters, hence needs redesigned TkrClusters first. Johann is working on this.
   
• I&T
  • BadStrips calibration
    • Done
  • ToT
    • TkrSplits are needed in order to apply ToT calibration.
      • First version of splits data is in the calibration database.
      • Code in TkrUtil is essentially ready to use the data.
      • RootPolicy issues need to be sorted out before we can use the new version of CalibSvc and start to debug the code.
    • ToT charge injection calibration
      • Mechanism to apply ToT calibration in simulation is mostly in place.
      • ToT calibration is not used in Recon (except crudely in AnaTup. This will be an R&D project, and will probably be developed in the context of the restructuring above.
      • Waiting for ToT Root file and associated database code.
    • ToT muon calibration
      • We need a procedure to produce constants from cosmic-ray data. (small R&D project)
      • Need code in TkrUtil to use the constants. (small job)
  • Validation of TKR geometry
    • Haven't worked on this yet. (but soon!)

     

• Tracker JIRA items
  • See Confluence page here (well, except that the confluence page appears to be broken)
    • Alignment (see above)
    • Restructuring TkrRecon (see above)
    • Event Filter (in progress, expect report from Johann at tracker meeting today)
    • Improving TkrRecon Website
    • Monte Carlo accounting of energy loss in Tracker
       
• FRED
   
• Cal Clustering
