In support of the Electron-Ion Collider (EIC) at Brookhaven National Laboratory (BNL), Jefferson Lab is contributing to the design of three satellite cryogenic plants. These satellite plants will augment BNL’s central plant, which currently provides cryogenics for the Relativistic Heavy Ion Collider (RHIC) at temperatures down to 4 Kelvin. The primary role of the satellite plants is to further...
Institute of High Energy Physics (IHEP) and Air Liquide Cryogenic China Science (ALCCS) have started a new Helium refrigeration plant to provide 1kW of cold power at 4.5K to cool-down the superconducting cavity to accelerate electrons. The cold box delivering this power was manufactured by ALCCS in China and connected to a KAESER compressor. The Helium expanders manufactured by Air Liquide...
High Energy Photon Source (HEPS) is a high-performance and high-energy synchrotron radiation light source with a beam energy of 6GeV and an ultra-low emittance of better than 0.06nm×rad. HEPS is mainly composed of accelerator, beamlines and end-stations, which would provide the synchrotron beam with will brilliance higher than 1×1022 phs/s/mm2/mrad2/0.1%BW. No less than 90 high performance...
The Shanghai high repetition rate x-ray free electron laser (XFEL) and extreme light facility (SHINE), a quasi-continuous wave hard XFEL facility, is currently under construction. The superconducting accelerators of SHINE require cryogenic cooling at 2 K for cavities, 5 K for cold interception, and 40 K for thermal shields, respectively. In this paper we present the overview and recent...
