Description
Rare Isotope Accelerator Complex for ON-line experiments (RAON) is the first heavy ion accelerator facility in South Korea. RAON consists of two main superconducting linear accelerators: SCL2 and SCL3. SCL3 cryogenic system was successfully completed the cryogenic commissioning in 2022 and maintained the stable cryogenic environment for the first beam commissioning in 2023. However, SCL2-IF cryogenic system has been installed without superconducting cryomodules and is awaiting cryogenic commissioning. The SCL2 cryogenic system is designed to cool not only the superconducting cryomodules but also the low temperature superconducting (LTS) magnets that are already installed in the In-Flight(IF) fragment separator. This paper will provide an overview and design of the SCL2-IF cryogenic helium distribution system, one of the main part of the SCL2-IF cryogenic system, and discuss the structure and methods used to cool the superconducting cryomodules and the LTS magnets.
