DISCUSSION ITEMS

  • Simulations - table of power deposition
  • Shielding and magnet model 
  • Hall A/C model and design/implementation 
  • Hall D design and radiation simulations
  • Other


PARTICIPANTS: Bogdan Wojtsekhowski, Hamlet Mkrtchyan, Josh Crafts, Steven Lassiter, Tanja Horn, Amy Comer, Gabriel Niculescu, Vardan Tadevosyan, Marie Boer, Rolf Ent,


SIMULATIONS - HEAT DEPOSITION (Gabriel)

  • Working on heat deposition table
  • power deposition in kW/cm3
  • Investigating issues with magnetic field
  • B from -10 to +20; maximum expected near center, but table shows it at the end of the magnet
  • If true, then may need 10 additional centimeters of cooling
  • average beam, gap is 3mm


SHIELDING MODEL (Josh)

  • Solved problem of facrtor of two - arithmatic error
  • lead 2391 bricks
  • Tungsten 2109 blocks
  • Total weight: 52.8 US tons (Lead, tungsten, borated poly)
  • Currently segmenting CPS in 2 block thick segments to illustrate stacking in more detail
  • Fidulization inside the model


DISCUSSION CPS PLANS FOR 2021

  • Order the magnet or order tungsten?
  • Need decision in ~3 months


NEXT MEETING: 15 JANUARY 2021, 8:00AM ET
