CERN Events Encourage Next Generation of Women in Science

In physics, as in many other branches of science, there is often a huge gap between the number of men and women. At CERN, for example, only 20 percent of the community are women. In an attempt to encourage and attract more women to choose science—and particularly physics—as a career,...

CSA Mourns Peter Gifford, a Friend, Colleague and Industry Leader

Peter Gifford, longtime leader of Cryomech Inc., has passed away at 69. Gifford was a fixture in the cryogenic community, a dedicated member of CSA and one of the second-generation industry leaders affectionately dubbed the “Cryomafia.” Under Gifford’s leadership, Cryomech has been a longstanding and strong supporter of CSA as...

CSA Mourns Kathryn Meyer

Her funeral was held on Jan. 28. Memorial contributions to the Fisher Center for Alzheimer's Research Foundation can...

What I Learned From My Mentors

CSA’s new board members reveal their most influential mentors in “What I Learned From My Mentors,” discussing where they worked together and ways the relationships advanced their careers.

Chart Industries Acquires Hetsco

Chart Industries, Inc. has acquired Hetsco, Inc. in a $22 million deal made through its subsidiary, Chart Lifecycle, Inc. The move, according to a Chart statement, supplements the company's current offerings by bringing a full suite of welding services for industrial gas and gas processing facilities including mission critical repair,...

Toward a Standardized ODH Analysis Technique

Standardization of ODH analysis and mitigation policy thus represents an opportunity for the cryogenic community. There are several benefits for industry and government facilities to develop an applicable unified standard for ODH. The number of reviewers would increase, and review projects across different facilities would be simpler. It would also...

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...

Definition or max temp which defines “cryogenic”?

Please help me with a definition: I am calculating material and fabrication costs for a quote for a hydrocarbon meter station.

Thermal shock on steel cylinder when dropped into liquid nitrogen

We are a research team at the University of South Florida, studying the “thermal shock” on a steel cylinder when it is dropped into liquid nitrogen. We want to make sure that the thermocouple does not get influenced by the surrounding LN2. Any advice?

Getter materials to absorb out gassed materials?

Here’s one for the scientists: We would like to sell vacuum insulated pipe for high temperature fluid applications. Are there any good getter materials that we can place in the vacuum space of our VJP to absorb outgassed materials at elevated temperatures?

Data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K.

I am looking for data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K. I would appreciate it if someone could give me some hints on where to find it.
