Agenda

• Initial Magnet Current scan results [1] (Garrett)
• Brief update on coil doses pdf (Juliette)
• Status of coil stresses pdf (Ruben)
• Status of upstream coil modifications (Ruben)

Minutes

Attendance: Juliette, Roger, David Flay, Jim Fast, Dave K., Garrett, Jay, KK, Naz, Probir, Qilull, Randy, Robin, Ruben, Sakib, Sandesh, Steve Wood

• Magnet scan
  • Probably don't need to go above 10%
  • can lower beam energy instead of raising the magnet current
  • 3 days to do the setup of 10% lower
  • go all the way to 4 pass 8.8 GeV
  • take on the worst case
  • look at r, dr/dz
  • look at other tiles
• Dose update
  • Estimate from this from SiO2 to cyanide esther or carbon (carbon fiber)
• Coil stresses and Upstream coil modifications
  • working on estimated stresses on various supports
  • slimming the upstream coil; add a 5th turn so NI is the same
• subcoil 4 power also
• Next meeting
  • July 2nd
