Actions

  • ACTION (Pasternak/Rogers): determine magnetic settings routine - do we imagine "equivalent coil"? Implement iron in MAUS? Run everything through OPERA?
  • ACTION (Rogers): Tolerances - controls people ask what are the tolerances on magnet current
  • ACTION (Rogers): EMR is misaligned by 10 cm; what is the implication for cooling channel acceptance

RLSR/MPB Actions

  • ACTION Rogers: Report, in a MICE note to the collaboration, the definitions and methods used for the determination of the betatron functions and emittances.
  • ACTION Rogers: Carry out an independent review of the beam dynamics analysis

Tolerances (Rogers)
  • Blackmore asks; how much does beta change over the length of the absorber?
  • Rogers notes; additional constraint should be quality of matching from tracker to EMR
Beamline (Blackmore)
  • Present u/s beamline looks optimal
  • Distribution is fixed, can only make the rate worse
Detector alignment (Hunt)
  • Looks like the tracker planes are in the wrong order at some point in the reconstruction chain; Hunt has fixed
  • Corrected alignment numbers are out in the issue tracker #1696
Magnet alignment (Rogers)
  • Another round of analysis has been performed
  • Still wip
PID (Pidcott)
  • Looking at PID on 7157; track matching is failing
  • Jan: Possibly needs scattering and dEdx? Possibly a "using legacy geometry" issue?
  • Blackmore: Possibly worry about particles clipping edge of diffuser
Physics Devil (Wilbur)
  • Couple of modifications to physics devil; added time stamps, separate html page for each run, detector efficiencies; uploaded in the next couple of days
Rate Analysis (Hunt)
  • First pass analysis done
  • Need to remove cuts based on downstream detectors; we are only interested in upstream detectors
