Analysis phone call, 15:00 BST, Thursday 28th May 2015

Phone Details¶

http://mice.iit.edu/phonebridge.html

Actions¶

• ACTION (Pasternak/Rogers): determine magnetic settings routine - do we imagine "equivalent coil"? Implement iron in MAUS? Run everything through OPERA?
  • 2015_01_Optics_Settings
• 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
