On July 17, 2023, during the LHC (Large Hadron Collider) beam operation for Physics Run 3, one of the low-beta superconducting quadrupoles located on the left side of LHC Point 8 (ITL8) experienced a quench following an electrical network disturbance. This quench unfortunately caused a crack in one of the magnet interconnection bellows, resulting in a significant leak between the cryogenic...
RAON (Rare Isotope Accelerator complex for ON-line experiments) is a heavy ion accelerator built under the Institute for Basic Science (IBS) in South Korea. The RAON facilities are composed of SCL3 linac (QWR cavity (81.25MHz, 4.5K) & HWR cavity (162.25MHz, 2K)) and SCL2 (SSR1 cavity (325MHz) & SSR2 cavity (325MHz), 2K). The total capacity of the cryo-plant is 17.7kW, divided between two...
The Cryogenic Distribution System (CDS) of PIP-II will distribute cryogenic helium from Cryoplant (CP) to the 23 SRF cryomodules for supporting various operating modes of the PIP-II accelerator. The CDS is being designed as a collaborative effort of Fermilab, USA and Wroclaw University of Science and Technology (WUST), Poland. The largest section of the CDS is the Tunnel Transfer Line (TTL)...
The Cryogenic Distribution System (CDS) is a key cryogenic sub-system of Fermilab’s upcoming Proton Improvement Plan II (PIP-II) accelerator, responsible for supplying cryogenic helium to support all of PIP-II operating modes and handling overpressure safety. The CDS is being designed and manufactured as a collaborative effort between Fermilab, USA and Wroclaw University of Science and...
Low energy linac(SCL3) of RAON (Rare isotope Accelertor comples for ON-line experiment) has been commissioned since 2023. SCL3 is composed of two types of superconducting cavity, which are QWR (Quarter wave resonator) and HWR (Half wave resonator). The stable operation of cavities was limited due to the imperfect performance of tuners in QWR cryomdules. Also, the various disturbances...
The cryogenic system for accelerator complex for ON-line experiments (RAON), is designed to maintain extremely low temperatures to support superconducting equipment, such as superconducting linear accelerators and low-temperature superconducting magnets. Proper operation of this system is essential for ensuring high efficiency, stability, and safety in the experimental processes. A robust...
