Meeting Time and Place

Tuesday, June 04, 2024, 1:00pm Hall D Counting House

  • Invited - Hovanes Egiyan, Stephanie Worthington, Keith Harding, Pavel Degtiarenko, Tim Whitlatch, Eugene Chudakov, Josh Ballard

Agenda

Minutes

  • Reviewed minutes from last meeting
  • Pavel has run the radiation and energy absorption (Fluka) for the latest absorber and shielding configuration
    • Currently it looks like no tritium issues with current design
    • Radiator position is currently 16cm upstream of the mahnet upstream steel face
    • Radiation levels at magnet coils are 2e4 gray for 10000 hrs running.
      • No need for expensive epoxy ($5K per gallon)
      • CTD-101K resin can be used - good for 1e6 gray minimum
      • Need to check on LCW quality of existing dump copper cooling skid for magnet compatibility
    • Pavel's new geometry has tapered steel upstream of absorber in X and Y - needs
    • Also taper in Y in Cu/W in magnet area - we will just use the exit size all the way through
    • New files with fine granularity in absorber high energy absorption areas are available - Hovanes will convert to usable files for ANSYS
    • New files for complete CPS power absorption available and Hovanes will convert
    • Tim will run new ANSYS models for the complete assembly
    • Tim learning FLUENT to verify cooling assumptions
    • There needs to be a collimator upstream of radiator
      • 1cm diameter hole
      • 15 cm deep in Z
      • OD of ? cm
      • About 10W absorption - no active cooling required
      • 80% W, 20% Cu
  • Looking at 3D model
    • Core assembly coming together
      • Meet with Alignment group Thursday to discus alignment/fiducialization plan
      • Looked at "birthday cake" stacking of steel - need features for stacking lead and heavy concrete
      • Copper absorber vacuum brazing test piece has been machined - will get tubing ready to braze in coming weeks
    • Air casters for moving - AeroGo coming to Demo system next week
  • Looked at 2025 install with MRI magnet and 2026 without MRI magnet just to show feasibility
  • Lead brick painting awarded - should be complete by end of September
  • Magnet Power Supply on schedule to be delivered March 2025
  • Magnet DeGauss test still scheduled for summer
  • Tim still writing and analyzing copper and tungsten thermal cyling data for ERR reply to Patrizia - hopefully a draft in 2 weeks
