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

RLSR/MPB Actions

  • ACTION Rogers: Review the requirements for accurate end-to-end simulation
  • 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
    • Optics review - cover the entire analysis
  • ACTION Rogers: Define strategies to provide online feedback, quickly

Have optics settings but need scaling factors to get to currents
  • Need to revise geometry for alignments, PRY effects, cool down and current limits
  • Note discrepancies between solenoid and flip mode on e.g CC
  • Need to check for uniformity in SS
    • Require setting that gives best uniformity and closest to 4 T within current limits
  • Need to track
  • Coil geometry should be referenced

EMR Paper awaiting comments
Pion contamination paper new data

Demo - awaiting optimisation from JB, paper getting in shape, circulate at next VC
  • John Cobb requests we consider Lithium not LiH for secondary absorbers
  • While we are at it Rogers throws in Be
  • John Cobb "figure of merit" H 1 Li 0.26 Be 0.17 C 0.09
Batch production
  • 3 pi 140
  • 3 pi 200 tracking through g4bl
AOB
  • Modules surveyed into the hall, Jason has the data
  • Surveyors will write up survey note; Ryan will pull survey data into MC in collusion with Victoria
