IEEE Announces 2013 CSC Award Recipients

The Council on Superconductivity of the Institute of Electrical and Electronics Engineers (IEEE) awards for 2013 were presented at the 23rd International Conference on Magnet Technology (MT-23) in Boston and at the 2013 International Superconductor Electronics Conference (ISEC 2013) in Cambridge MA.

Cryopump Systems and Space Telescopes

In the 21st century, NASA and the world have started looking into deep space astrophysics. Acquiring deep space images requires a space telescope with a large optical mirror, such as the James Webb Space Telescope (JWST), the Planck telescope, the Herschel telescope, etc. To carry out various space missions at...

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...
