Tracker Reconstruction
Alignment

• Work begun originally by Hiro Tajima. See the following links for more information (earliest to most recent):
  • Alignment studies (9/12/2002) (pdf)
  • Plan of tracker alignment studies (11/25/2002) (pdf)
  • Tracker alignment with cosmic rays (12/02/2002) (pdf)
  • Transformation of tracker alignment parameters (3/18/2003) (pdf)
  • MC study result of tracker tower alignment (4/28/2003) (pdf)
  • Updates on MC study of tracker tower alignment (6/30/2003) (pdf)
  • Status of tracker tower alignment (7/15/2003) (pdf)
     
• TkrRecon group is passed current code for incorporating into Gaudi framework
  • Make into own cvs package: TkrAlignment
  • Algorithms/methods to run off TDS data objects instead of from root
  • etc.
     
• An attempt to describe the the tower alignment offsets and rotations and how to relate between local and global coordinate systems is located here (ppt, pdf)
   
• Other techniques to consider:
  • CHEP03 paper outlining an analytic approach (pdf)
