Software & Computing Issues¶

• Software
  • TOF:
    • S. Wilbur is now TOF code & calibration maintainer. Calibrations performed against data from last cycle.
      • Need robust validation procedure before uploading.
  • Tracker:
    • NaN bug: bug identified, fix is not yet in MAUS
  • Global:
    • Performance is an issue; believed to come from propagation; Jan Greis studying
  • MC:
    • G4BL generation of pion beam libraries started -- issues with very few pions getting through to TOF1/Tracker.
      • Possibly related to incorrect dipole strengths in g4bl deck. Needs to be studied

• Infrastructure
  • by-run geometry of recent data did not have absorber in
    • does not affect bare reconstruction -- but will affect propagation & MC
  • Geometry has now been updated.

• Data processing
  • All StepIV data processed with MAUS-v2.6.0
  • Automatic data processing of all recent data completed with MAUS-v2.6.1
  • Run-by-run online reconstruction plots are now bundled with reconstructed output, as well as with the raw data tarball.

• Reprocessing
  • Geometry update (with LiH in), and new TOF calibrations (running checks) warrant reprocessing.
    • reprocessing will commence by Thursday (11/3), with a new MAUS tag, and will be back-loaded so new data gets reprocessed first

• Personnel
  • DAQ head
  • Geometry head
