A large-scale helium refrigeration system is under designing by Rare Isotope Science Project for a new superconducting Linac, RAON. Heat loads of cryogenic components including cryomodules for superconducting, LTS magnets for IF (In-flight) Separator, and helium distribution system are predicted. The coldbox will supply 4.5 K supercritical helium and 40 K gas helium to each cryomodule through the distribution system. The cavities will be cooled at sub-atmospheric temperature, 2.1 K which is generated by recuperating systems in each cryomodule. 40 K helium is also used for the cooling of HTS magnets which will be installed at the front section. This paper presents current status of the helium refrigeration system for RAON.
