Schedule

Detectors

  • Detector integration (D. Rajaram)
    • Reconstruction quality flags (A. Dobbs to make requests to detector groups) #1585
  • Tracker (P. Kyberd)
    • PRIORITY INTERRUPT C. Hunt email 18-08-2015:
      "After a lot of playing around, and seeing how the tracker reconstruction correlates to the TOF reconstruction, it seems that the output from the track reconstruction is incorrect and requires a rotation of 120 degrees and a sign flip to correct it. If you sit and think for a while you can justify this as being the result of the planes being in the wrong order. However as the data is not specifically sensitive to the plane ordering it could be one of 3 things:
      - Construction differs to design
      - Recon geometry differs to construction
      - Mapping differs to construction and recon geometry"

      K. Long keen we pursue as matter of urgency

Detectors

  • Detector Integration
  • KL
  • Ckov
    • AL has begun work on CKOV, in particular MC digitisation, will give a report at next meeting on progress
  • EMR
    • FD has submitted first reducer code, working to get into trunk
  • Tracker
    • Plane ordering ambiguity is a major issue, need to resolve asap
    • PK will send schedule update to AD
  • TOF

Global Reconstruction

  • PID blocked by track matching, track matching blocked by tracker plane issue

Unpacking

Infrastructure

  • Geometry
    • RB now has latest files from J. Tarrant, starting to update CDB, working on getting update into MAUS as well
    • AD requests RB to find source of v. large SOAP error messages and fix
  • MC
  • G4BL
  • GRID
    • GRID processing bug fixed, hopefully processing will restart this week
  • Other
    • trunk now builds with GCC 4.9

Online

  • libmonitor.tarz has been failing its checksum. Will update checksum and move source from Geneva to micewww machine

Performance

Miscellaneous

  • PK asks how we can ensure integrity of parameters held in CDB, how to make sure they are correct for each run, etc. PK to make MICE mine to start debate
  • Workbook now in the trunk under doc/
