New X-ray laser technique could reveal atomic detail of proteins

Use of the Linac Coherent Light Source has led to the development of a unique X-ray laser innovation at the Department of Energy's SLAC National Accelerator Laboratory that may make it easier and faster for scientists to fully map medically important proteins whose structures have remained stubbornly out of reach.

Restoring the Foundation: The Vital Role of Research in Preserving the American Dream

“Restoring the Foundation: The Vital Role of Research in Preserving the American Dream,” a 154-page report released by the American Academy of Arts and Science, reinforces many of the findings and recommendations of the 2005 report “Rising Above the Gathering Storm.” The earlier report focused on the causes of America’s...

Boom Awardees Making Headlines

The Cryogenic Society of America is very proud of the recipients of our Roger W. Boom Award. Over the years since 1996, we have watched as our awardees have moved ahead in their fields, living up to the promise the Boom awards committee saw in them. We caught up with...

Frozen Aliens and Superpowers

Liquid nitrogen is cool. That’s a classic pun, but it’s also true. Liquid nitrogen is dramatic and a little bit dangerous, and its startling effects on everyday objects are immediate, making it a fantastic tool for science education and outreach.

LHC experiments join forces to zoom in on the Higgs boson

For the first time, CERN's ATLAS and CMS have presented a combination of their results on the mass of the Higgs boson--on March 17, 2015, during the 50th session of “Rencontres de Moriond” in La Thuile Italy. The combined mass of the Higgs boson corresponds to a measurement precision of...

Neutrons provide first images of refrigerant flow

Using noninvasive techniques, researchers at DOE's Oak Ridge National Laboratory have captured undistorted snapshots of refrigerants flowing through small heat exchangers, helping to further elucidate characteristics of heat transfer.

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...
