Tracker Recon Report
Analsysis Group Meeting
Aug 2, 2004
 

• Alignment
  • Finishing the work to integrate the standalone single tower alignment into  the Gaudi environment
  • Some "annoyances" encountered in converting Hiro's original code...
    • Most problems now dealt with resulting in a few simplifications
      • e.g. use TkrRecon clusters and track fitting utilities
  • Attempting to connect directly with Leon's TkrAlignmentSvc
  • This has taken me longer than I thought it would... but about ready for testing now
     
• Re-structuring TkrRecon
  • Current focus on implementing new TDS classes in the Event package
    • Plan is to implement "new" (restructured?) TkrCluster and TkrKalFitTrack TDS classes
      • TkrCluster highlights:
        • TkrClusterCol to become solely a container
        • Use relational tables (or something similar) to provide access to clusters in "standard" groups
          • Tower, x-y pairs, plane, etc.
        • Highlights of considerations for a new TkrCluster class can be found here
        • Johann/Leon now developing the new version
      • TkrKalFitTrack highlights:
        • Content mostly unchanged
          • Key changes include keeping a smart pointer to cluster instead of index, keeping volume identifier instead of tower, layer, view, ...
        • Primarily changing access methods for hit information
          • TDS object now contains data, methods to operate on the data moved to external routines
            • In particular, chi-square and energy loss calculations moved out of TkrFitPlane class
        • Restructure inheritances to fix problem (?) current structure creates for Gaudi converters
          • Also, dropping our previous goal of a single track fit base class for any future imagined global reconstruction algorithm
            • When we got one we'll deal with it
        • Big change: dropping TkrPatCand TDS class,  output of pattern recognition will be a TkrKalFitTrack to be sent to the fitter for final fit
        • Highlights of considerations for a new TkrKalFitTrack class can be found here
        • New version under development
      • TkrVertex is also under consideration, longer time scale here
        • Bill is looking into this now
    • First step (post redesigned code): Make the existing code work with the new TDS classes
  • Since TkrRecon is undergoing modification, have been asked by the core group to consider also modifying the package structure.
    • See  Traudl's guidelines here
       
• I&T (Leon)
  • Ntuple documentation: I've added the seven new AnaTup variables that have appeared since DC1. We still need a strategy for keeping track of (the not necessarily synchronized) versions of AnaTup and merit.
  • Bad Strips calibration: some refinements. Configuration (EM, EM2, 2-tower LAT, etc.) is now set from options file.
  • Working on revamped TkrCluster class, including new information for ToT. (See above.)
  • Alignment: working on code to apply alignment constants at during recon.
  • Geometry: a new engineer, Steve Lundgren, will be helping with the geometry verification.
     
• Tracker JIRA items
  • See Confluence page here
    • Alignment (see above)
    • Restructuring TkrRecon (see above)
    • Event Filter (in progress, expect report from Johann at tracker meeting today)
    • Improving TkrRecon Website
    • Full Monte Carlo energy accounting in the  tracker
       
• FRED
  • Continuing improvements to Tracker display for FRED
