  • in discussion with TOKIN about specifications and tolerances - concerns about stated tolerances applied to geometric dimensions on flatness and parallelism; conductor cleaning
  • CPS Tosca model updated to include bolt holes and cutouts
  • Prototype (Dean)
  • on site, machined and assembled
  • Working on reqs for yoke and pole
  • Yoke: 1010; pole: supermendur
  • working towards deadline - beginning August for end of year clearance
  • Insulation material and radiation hardness
  • glass resin made for Japanese magnet
  • max expected is MRad, but material should be resistant up to GRad levels
  • Started discussions with Hall D about design models


MAGNET DESIGN/ASSEMBLY (Bert)

  • Drawings almost done for yoke and pole
  • identifying vendors
  • Assembly steps outlined

  • fasten coil to side yoke and shim; install
  • fasten lower yole to stand
  • check gap on coil
  • add shims - mm of clearance to be accounted for
