ERL SRF CRYO MODULES

AND CRYOGENIC SYSTEM

G-5 and final ERL configuration

Cryogenics system identical, except elevation change of SCRFGun requires rework of piping to Gun cryomodule

Helium supplies 3 atm, 4.5K helium to cryomodulesThermal Transition InterceptsCavities Reservoir bathRecovery heat exchanger to recovery ref between 2K and 4K. Low pressure helium return through ambient vaporzier to warm process vacuum pump
