April, 2009 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 cryomodules Thermal Transition Intercepts Cavities Reservoir bath Recovery heat exchanger to recovery ref between 2K and 4K. Low pressure helium return through ambient vaporzier to warm process vacuum pump LN2 distribution to cryomodule shields and Cathode cooling G-5 CRYOGENIC SYSTEM
