DISCUSSION ITEMS

  • Design models, stress/thermal calculations
  • Engineering analysis and planning
  • TCS updates
  • Other


PARTICIPANTS: Amy Comer, Arshak Asaturyan, Bogdan Wojtsekhowski, Donal Day, Rolf Ent, Hamlet Mkrtchyan, Marie Boer, Petr Stepanov, Tanja Horn, Tristan Anderson, Vardan Tadevosyan

DESIGN/ENGINEERING (Steven, Amy, Bogdan)

  • Copper absorber prototype modeling and FEA ongoing
  • initial results of the simulations summarized in ppt slides - checking different scenarios
  • some details need to be further investigated, but overall looks promising
  • Quote requests for the copper absorber have been sent out to vendors
  • Fluent model - good progress
  • Bert has been working on updating the coils and magnets to the longer lengths
  • Waiting for response from Elmet before making decision on how to proceed with Tungsten blocks
  • bids are coming higher than estimated, so far no information received from Elmet
  • Additional lead bricks will be available from MIT-Bates
  • Gabriel will check optimal position of tungsten/lead with simulation


TRANSVERSE TARGET MAGNET UPDATE

  • From Chris K.: Scientific Magnetics is making good progress
  • coils are assembled and quench protection circuitry is in place - will be wired next week
  • Vacuum chamber and cryocooler are assembled and have been successfully tested (no leaks, pulse tube reached <4K, etc.)
  • Magnet will be installed in the cryostat in September
  • A few cooldowns are expected to optimize placement of shims and to reach the required field uniformity
  • Action: ask Chris K for update on shims, field uniformity, etc. sometime in September


TCS TRACKING UPDATE (Vardan)

  • Investigated backtracking to account for deviations from linear regression
  • Both methods of tracking give very similar results - backtracking works a little better, dependend on momentum
  • Need to check on magnetic field sign outside target


NEXT MEETING: FRIDAY 24 SEPTEMBER AT 8AM ET
