Software & Computing¶

• S/w and computing performed smoothly during Sep-Dec running.
  • Some minor issues with EMR dropouts and DAQ errors at high rates.
  • low-level monitoring did not show any issues with tracker/detectors

• Software
  • MAUS version 3.0.1 during Nov-Dec runs.
  • Several changes since then:
  • Tracker:
    • Issues were found with the MINUIT PR fitter. Reverted to LSQ. PR upgrades by CH to minuit fits.
  • Globals
    • several updates to track matching & structure: storing raw sp/tracks with global counterparts, energy loss calculation for propagated tracks
  • Geometry:
    • Fixes to LH2, LiH models, updated survey information, added extra virtual planes for global track matching
  • New MAUS release with these changes is in progress.
  • Some issues still remain:
    • Fields: disagreement between hall probes & field descriptions needs to be understood (hall probe positions, field map)
    • TOF: inefficiency in TOF2 and systematic offset in deltaT -- most likely arising from calibrations

• Data processing
  • Re-processing of all StepIV data is awaiting MAUS release
    • Will include globals as default. (during data-taking we did fast-processing without globals + slower globals production)
    • Victoria's 7469 has been reprocessed with trunk. Checking performance.
  • MC production with new release & updated geometry awaiting MAUS release
    • Need to figure out how (many) systematics-MCs are produced
