  1. Generic Cryo HX Options R. van Weelderen (CERN)

  2. Cryo Generic Layout Possibilities • Inner triplets will be actively cooled via 2 parallel HX • D1 and MCBXC cooling could be either active as well or passive via conduction • Options considered: • D1 and MCBXC passively cooled • D1 passively cooled • All actively cooled • Room for cryo services needed at: • Q3 to MCBXC (option 1) • MCBXC to D1 (option 2) • D1, non-IP end (option 3) • Entry at D1, non-IP end + D1 bypass to a)/b) (option 1/2)

  3. Two Phase HX Inner Diameter Options • Assumptions: • Total heat load of D1 + MCBXC and IT: 500 W in all configurations • Cold source at IT pumping line: 1.800 K • T-budget for HX of actively cooled magnets: up to 2.000 K • T-budget for conduction cooling: 50 mK (from 2.050 K to 2.000 K) Consequences: The two-phase HX sizing is mainly dependent on total heat load: 68 mm ID in all cases For all actively cooled magnets and interconnects the HX’s must be fully continuous (no bends allowed!) Thermal budget for actively cooled magnets (coil – HX): ~ 170 mKmax (Tλ – 2.000 K) Thermal budget for passively cooled magnets (coil – HX): ~120 mKmax (Tλ – 2.050 K) Piping through magnets & cryostats to be sized (complete PID to be made) depending on choice of Cryo implementation
