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
  • ACTION Rogers: Define strategies to provide online feedback, quickly

Magnetic settings
  • Some factors pushed
  • Problem around the focus coil possibly due to model error?
  • Pretty linear, some small non-linearity/saturation between flip and non-flip
  • Cryogenic dimensions
  • In-hall positions
Tracker alignment
  • Scott: use two tracks to get z-position?
  • John Cobb: add in lH2 window
  • Tracker scattering - check I did upstream and downstream
