Big scientific facilities which use cryogenic technologies usually need to transfer cooling power from one or several cryogenic plants to cryogenic users. Typical cryogenic users are cryomodules with superconducting radiofrequency cavities and cryostats with superconducting magnets that are immersed in liquid helium. Due to the complex architecture of the cryogenic systems, the cold helium...
The multi-process pipe vacuum jacketed cryolines for the ITER project are probably world’s most complex cryolines in terms of layout, load cases, quality, safety and regulatory requirements. The risk mitigation plan of Indian Domestic Agency (IN DA), who is responsible for the supply and installation of ITER cryolines, included design, manufacturing and testing of prototype cryoline (PTCL)...
Johnston couplings are used for detachable connections of flexible cryogenic transfer lines to stationary plant components. There are different solutions for this purpose, the technical design of which differs mainly according to the utilized fluid properties and the connection dimensions. Within the framework of a project for the MITICA facility, meant to test in advance the ITER Neutral Beam...
A hybrid magnet which is capable of producing more than 40 T steady field has been put into operation eraly this year at CHMFL. The superconducting outsert of the hybrid magnet is wound with Nb3Sn CICC and cooled with forced flow supercritical helium at 4.5 K. A multi-channel cryogenic transfer line is mounted between the magnet cryostat and the cryo-distribution box to transfer supercritical...
Meyer Tool & Mfg., Inc (Meyer Tool) of Oak Lawn, Illinois is manufacturing a cryogenic distribution box for Fermi National Accelerator Laboratory (FNAL). The distribution box will be used for the Muon-to-electron conversion (Mu2e) experiment. The box includes twenty-seven cryogenic valves, two heat exchangers, a thermal shield, and an internal nitrogen separator vessel, all contained within a...
The heat leakage of cryogenic transfer lines directly influences the performance of the large-scale helium refrigerator. In this paper, the thermal mode of cryogenic transfer line considering temperature distribution and heat leakage of support and multilayer insulation was established. To validate the model, the test system of cryogenic transfer lines with good thermal shield and changing...
Since the conceptual design review of the ITER Cryodistribution (CD) many modifications and changes have been applied due to both system optimization and improved knowledge of the clients’ requirements. The CD, consisting of one Cryoplant Termination Cold Box (CTCB), five Auxiliary Cold Boxes (ACBs) and one Thermal Shield Cold Valve Box (TCVB), distributes the cooling power generated in the...
The helium recovery and purification system at the IHEP is build to recover and repurify helium containing 10% water saturated air at a rate of 210 Nm3/h and a pressure of 1.05 bar to a contaminant level below 5ppm. Low pressure gas is recovered through a pipeline from the BEPCII cryogenic system, ADS-inject I cryogenic system,and other cryogenic equipment test which evaporate the impurity...
