Actions¶

• ACTION (Pasternak): 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
  • http://mice.iit.edu/micenotes/public/pdf/MICE0474/MICE0474.pdf
• ACTION (Drielsma/Rogers): EMR is misaligned by 10 cm; what is the implication for cooling channel acceptance
• ACTION (Rogers): Effect of addition of Aluminium windows to the MICE Demo geometry
  • Jaroslaw did a study previously

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

General agreement that outline run plan is sensible for Friday
Tracker group will make tracker shifter, may go in with physics shifter
Tracker alignment/rotation is ongoing

• No update or decision
  Discussed simulation issues
• Noted CDB workaround to deal with no currents in CDB
• Suggest running single "200 MeV/c" particle down the beamline axis is sensible
  Issue in tracker DAQ!!
• Noted that this is a thing
• Introduces significant systematic bias in all current data taking
