Agenda

• Tyler Quad tune in g4hrs
• Ryan Optics Update
• Dustin Quartz thickness (if time)

Minutes

• Tyler has g4hrs up to date in repository
  • Did return for focus at 0.9m downstream from VDS
  • Better agreement with Ryan's hrstrans matrices now
  • Central ray downstream of HRS dipole offcenter in quads - no way to recenter both position and angle

• Ryan comparing sieve data
  • Mistune data doesn't match HRStrans
  • Reconstruction matrices not redone in calibration, so target variables will be distorted
  • Suggest looking at reproducing data with misreconstructed simulation
