Software & Computing Issues¶

• Software
  • There was issue with geometry missing diffuser material -- fixed
  • Tracker-tracker misalignment seen (again) -- under investigation
  • TOF discrepancy ~100ps between truth and reco -- under investigation
  • Momentum discrepancy ~ few MeV between data/MC -- under investigation

• Data reprocessing & MC production
  • Step4 data routinely reprocessed with each new MAUS release
  • Reconstruction quality monitoring and flagging being developed
  • MC: will need new G4BL input beam libraries once the pion beamline optics is finalized
    • Starting to look at changing the G4BL-MAUS interfacing to be more efficient
  • MC speed issue remains
    • for now circumvented by throwing computing resources at it

• Infrastructure
  • Improvements to make interfacing between cooling channel DB <-> RunControl more robust
  • DB structure & API for holding absorber information (to be set from RC) -- developed, now being tested
  • Reconstruction quality table (see above) developed -- to be tested

• Online
  • Prototype prescale-trigger design developed
    • Reconstruction software changes required to handle this
