Meeting 3 December 2021

Discussion items:

• Magnet design and tests

• Status of tungsten and lead blocks

• TCS updates

• Other

PARTICIPANTS: Steven Lassiter, Dondal Day, Bogdan Wijtsekhowski, Erik Wrightson, Hamlet Mkrtchyan, Tanja Horn, Marie Boer, Rolf Ent, Vardan Tadevosyan

MAGNET DESIGN AND TESTING

• In model added heating elements on top to reach larger temperature range for testing and evaluated

• Copper brazing concept design

• Temperature profile with two 1.2 kW heaters Tmax=893degC, Tabs=221 degC

• still evaluating stresses, displacements, etc.

• Temperature profile for two 2kW heaters

• Heater element would have melted Tmax=1460degC (Copper meltung point 1085 degC), temperature along top absorber is 330degC
• stresses, displacements look fine

• Validating Fluent model with by-hand calculations

• water flow, pressure, etc.
• key for moving forward

• Global timeframe towards magnet design

• need global review of the magnet (resistor, fluid dynamics)
• anticipate to start bidding in a few months
• when magnet designed can start designing insert etc.
• also want to do tests to see how much power can really withstand, etc.

TUNGSTEN BLOCKS

• first delivery expected in January

LEAD BLOCKS

• expect 7-8 tons, but not yet received

HALLD

• At some point share CPS design with HallD engineering team - note that HallD needs 60kW but magnet can be longer

• HallA/C: compact design since close to target
• HallD: in tagger area - more space

TCS UPDATES (Vardan)

NEXT MEETING: FRIDAY JANUARY 14TH, 2022 AT 8AM ET
