Cryogenics

Convener: Dr Laurent Tavian, CERN

The FCC cryogenics will require large refrigeration and cryogenic distribution systems. The refrigerator unit-size (~ 100 kW equivalent at 4.5 K) is four times larger than the present state-of-the-art and the refrigeration cycles will require operating pressures up to 50 bar and centrifugal compressor (cold and warm). The 100-km distribution system is based on invar technology avoiding the use of risky and expensive compensation units. Concerning instrumentation, 8000 cryogenic valves (ranging from DN10 to DN250 and from PN10 to PN50), 850 cryogenic flowmeters, 12’000 cryogenic thermometers (ranging from 1.9 K to 300 K) will be needed in total. Large storage capacity will be deployed in order to store the 880-t helium inventory in liquid form (~80 % of the inventory) and 20-bar gaseous form (~20 % of the inventory).
