The Dalian Advanced Light Source (DALS) test facility has completed the com-missioning of the cold box in June 2024, and the first cooldown of the distribu-tion system began in September of that year. The whole cryogenic system re-quires helium inventory of 1.4 tons. For a more rational use of this helium, the helium distribution and the total inventory in the system are monitored, and a tool...
Water contamination represents a critical challenge in helium cryogenic systems, presenting multifaceted operational risks for advanced industrial and scientific facilities. These water contaminants undergo complex phase transformations during system operations, crystallizing under extreme low-temperature conditions and posing significant threats to precision engineering infrastructure. Such...
Ability Engineering Technology (AET) has developed a system capable of receiving helium at very low concentrations (less than 10% by volume) and effectively separating out undesirable gases to yield high purity helium (5.0 – 6.0 grade) at high recovery rates (greater than 90%). This is accomplished with membrane separation and a subsequent cryogenic adsorption process. The operational...
The increasing need for optimal and sustainable use of cryogenic resources to support Fermilab’s scientific mission has highlighted the necessity of improving the Laboratory’s helium management practices. An assessment of cryogenic test facilities identified the Technical Division’s Industrial Building 3a (IB3A) as a key site requiring upgrades to integrate a helium recovery system. The IB3A...
