Stability
Stability refers to the ability of a device employing superconductors to remain in its superconducting state after part of the superconductor transitions back to its normal conducting state due to a disturbance. While the concept can apply to many superconducting devices—transmission lines, generators, motors, etc.—it is most commonly considered in...
Cable-in-Conduit Conductors
Cable-in-Conduit Conductors (CICC) are a common form of superconducting cable used in large-scale applications. There are several varieties of CICCs, but they all consist of many small, stabilized superconducting wires contained within a conduit through which a coolant (typically supercritical He II) flows. Figure 1 shows the cross section of...
Bayonet Coupling
A bayonet coupling is a demountable joint that allows for quick and easy connection and disconnection of cryogenic components, including transfer lines, cryostats, liquefiers and refrigerators. Bayonets provide a number of advantages, chief among them the ability to connect and disconnect the bayonets while components they connect are still at...

Bose-Einstein Condensate
A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...
Cold Technology for Pest Control
While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...
Cryogenic Finishing
The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...
Looking for the thermal conductivity of the high density polyethylene (HDPE) between 1.9 and 10K
I am looking for the thermal conductivity of the high density polyethylene (HDPE) between 1.9 and 10K (or even up to higher temperatures). The best would be to have these data for the HDPE material which sold by the CERN shop, which has a density of 0.95 g/cm3. Pier Paolo...
What is "Alpha" cryogenic processing?
Can somebody please tell me what the “Alpha Cryogenic Process” is? How is it different from ordinary cryogenic processing? Bernd Ahne, HiFi-Tuning
Do Stirling coolers have any relation to Stirling engines?
I was just wondering, do Stirling coolers have any relation to Stirling engines?
What type of MLI should be used in LOX (VJ) lines and flex hoses?
I work for ASRC Aerospace at the Kennedy Space Center (KSC). We support NASA in ground support equipment (GSE) design. I have a question concerning the type of multilayer insulation (MLI) to use in LOX vacuum Jacketed (VJ) lines and flex hoses.
