CGA Announces New Process Safety Committee

In an email to its members, the Compressed Gas Association announced the formation of a new Process Safety Committee to address process safety concerns and gaps that affect the industrial gas industry.

Auguste Acquires Taylor-Wharton’s European Operations

Auguste Cryogenics SK s.r.o. has acquired Taylor-Wharton International’s European Operations, including a cryogenic pressure vessel manufacturing facility, Taylor-Wharton Slovakia s.r.o., and the related warehouse and office complex of Taylor-Wharton Germany GmbH. Auguste says all employees have been retained and that the facilities will continue to operate under the Taylor-Wharton brand...

XFEL Commissions New X-ray Laser

Engineers at European XFEL, a large international research facility with 11 European member countries, have begun commissioning a 3.4-km-long underground X-ray laser. When operational, the laser will generate extremely short and bright X-ray light flashes that will enable new views of the structure and fast processes of the nanocosmos. Applications...

2016 Nobel Prize in Physics Awarded

The Royal Swedish Academy of Sciences awarded the 2016 Nobel Prize in Physics to David J. Thouless, F. Duncan M. Haldane and J. Michael Kosterlitz, three laureates who have used advanced topological methods to study unusual phases of matter, such as superconductors, superfluids or thin magnetic films. Thanks to their...

Spallation Neutron Source Marks a Decade of Research

Oak Ridge National Laboratory (CSA CSM) celebrated a decade of research at its Spallation Neutron Source (SNS) with an event on September 22. The SNS features a linear accelerator and accumulator ring. It sent the first protons to its one-of-a-kind mercury target in April 2006 and over the last decade...

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...

You are encouraged to read Cryo Central’s History...

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...
