Meeting 16 April 2021

DISCUSSION ITEMS:

• Design models, power deposition/stress calculations

• TCS updates

• Other

PARTICIPANTS: Hamlet Mkrtchyan, Josh Crafts, Steven Lassiter, Vardan Tadevosyan, Tanja Horn, Amy Comer, Arshak Asaturyan, Rolf Ent, Marie Boer, Bogdan Wojtsekhowski, Igor Strakovsky,

POWER DEPOSITION AND STRESS/THERMAL CALCULATIONS

• calculation results look similar (Bogdan/Steven)

• heat transfer/cooling efficiency - calculations ongoing

• Action items:

• work out engineering analysis and plan
• conceptual design report

• stress analysis and other considerations
• design parameters
• material behavior under irradiation (neutron flux 10^12 neq/cm^2)
• review by experts, e.g. beam dump experts from SLAC

• Discussion CPS time frame

• 2021/22: magnet conceptual design and tungsten block
• Need ~2-3 years to assembly
• Anticipated completion ~2024/25

TCS UPDATES

• Investigation of smaller time window

• with aggressive timing cuts can get to acceptable data rate (20 ns --> 60kHz --> ~15 kHz)
• need to confirm that data quality remains good (correlation plot)

• Action items:

• demonstrate exclusivity including all physics backgrounds

• For physics background could check with single pi0 analysis in Hall D/B

NEXT MEETING: FRIDAY 30 APRIL AT 8AM ET
