The cryogenic helium plant for SCL3 section of Korean heavy ion accelerator (RAON) has been successfully operated in approximately 16,000 hours during past 3 years. Therefore, several maintenance activities are necessary to prevent any failures and keep the performance of the cryogenic helium plant. The maintenance items are divided with two parts according to its characteristics. The first...
The LCLS-II X-ray light source, powered by a 700-meter superconducting LINAC, is supported by two 4 kW @ 2.0 K cryoplants. The first cryoplant, commissioned in 2021, successfully cooled the LINAC in March 2022. This paper provides a detailed analysis of the cryoplant's operational performance and reliability over the subsequent three years of continued operation. Key metrics, including Mean...
Jefferson Lab operates two large (18 kW at 4.2 K equivalent) central helium liquefiers (CHLs) in support of its upgraded 12 GeV electron beam accelerator. Both machines utilize full cold compression from the saturation pressure at operating temperature (approximately 2.1 K) to just over atmospheric pressure. The original plant, CHL1, was recently outfitted with a replacement subatmospheric...
In the context of the energy transition, numerous cryogenic applications - both historical and emerging - such as the long-distance transport of electricity from offshore wind generation or hydrogen mobility, require the use of compact, flexible and efficient cryogenic systems.
The TurboBrayton technologies proposed by Air Liquide advanced Technologies for more than fifteen years have met...
