Software & Computing Report¶

• Software
  • Tracker:
    • NaN bug: bug identified, pending fix in MAUS trunk
    • Charge reconstruction bug: has been flagged, tracker group to investigate
  • TOF:
    • Discrepancy between TOF & tracker of ~100 ps: Scott Wilbur starting to investigate by looking at TOF0-TOF1 path-length effect
  • Global:
    • Data structure issue was holding back global track matching from going into production processing.
      • This has now been fixed. But -- initial performance benchmarks indicate slowness - being investigated.
    • Need to account for PRY effect in MAUS fields -- cumbersome (no manpower) to generate OPERA maps for each current setting
    • Correction factors (at 4T) received from HW/JP
    • Need to run some sample reconstruction with different scale factors to test
  • MC:
    • G4BL generation is bottle neck.
    • FD to look at this next
      • Consider TOF0 as G4BL-MAUS handoff point -- needs to be tested by pushing through both G4BL & MAUS and comparing

• Infrastructure
  • CDB structure & associated software API have been created to hold alignment/analysis-based corrections to geometry
    • RB is testing
    • corrections will be applied at geometry download time, transparent for end-user.
  • Reconstruction quality table has been created along with API (JM)
    • Reco flags will come from a post-processing job
    • DR developing post-processing & quality extraction infrastructure. Also merging physics devil functionality into the post-processing job

• Data reprocessing
  • Data to be re-processed with next MAUS release once tracker bugs are fixed
    • may not have Global in this iteration if performance continues to lag data-rate
  • will like to have alignment corrections coming from the CDB table (above) for this round of processing
