Agenda

• Coil down-select (est. Aug. 28, 2020)
  • Physics summary document
    • all simulations completed
  • Pugh matrix for eng. factors, cost and schedule
  • Change control board
    • review Ruben's recommendation
    • make a decision
• Design and alignment tolerances
  • worst-case scenarios are tolerable
  • independent of the coil type (seg. vs. hyb.)
  • Recommendation should be closed - the method is developed
  • single coil offset studies still planned
• Overall tolerance document (in progress)
  • some sims needed to clarify items in document
  • will present at a later meeting
• Doses on coils/epoxy/braces
  • preliminary study done a couple years ago
  • repeated with updated exp. geometry
    • still rough (but conservative) on order of 100 MGy
• Stray field study related recommendations
  • Develop a magnetic measurement plan
  • Evaluate need for full field map
  • Tolerances for alignment should include clean transport of beam
• Magnet maximum current specification
  • Design vs. operational limit
  • design current is 20% above operating current for 11 GeV beam at nominal temperature
  • matters for specification of KPP (key performance parameters)
• Other business
• Next meeting

Thanks,
