Frederick J. Edeskuty, expert on cryo safety, dies at 89
Frederick J. Edeskuty, 89, long-time CSA member, Cold Facts columnist and expert on cryogenic safety, passed away on Friday, May 10. After receiving his doctoral degree in chemical engineering and physics at the University of Minnesota, he moved his family to New Mexico where he began a 40-year scientific career...
DOE Approves Freeport LNG Non-FTA Export Application
The US Department of Energy has conditionally authorized Freeport LNG Expansion, and FLNG Liquefaction, LLC (Freeport) to export domestically produced liquefied natural gas (LNG) to countries that do not have a Free Trade Agreement (FTA) with the United States from the Freeport LNG Terminal on Quintana Island, Texas.
Revolutionary muon experiment to start with 3,200-mile move of cryostat from Brookhaven to Fermilab
Scientists from 26 institutions around the world are planning a new experiment that could open the doors to new realms of particle physics. But first, they have to bring the core of this experiment, a complex electromagnet that spans 50 feet in diameter, from the US Department of Energy's Brookhaven...
DESY awards contract for 120 RF cavities
RI Research Instruments GmbH, a majority-owned subsidiary of Bruker Energy & Supercon Technologies, Inc. (BEST), announced the award of a contract for five radio frequency (rf) cavities for the Facility for Antiproton and Ion Research (FAIR) project, valued at approximately $5.8 million.
Use of cryoablation for treatment of breast cancer shows promising results
IceCure Medical reports that Dr. Eisuke Fukuma has treated 58 breast cancer patients with cryoablation over the last six years under a research protocol at Kameda Medical Center in Japan. As of now, they say, none of the patients have had a tumor reoccur or distant metastases. By choosing this...

Space Cryogenics
Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...
Exergy
The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...
Cryogenic Treatment
Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...
Air Separation and Liquefaction

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...
Power usage: cryogenic systems vs. regular refrigerators
A recent project highlighted to me that closed cycle cryogenic cooling systems use far more electrical power to reduce temperatures by a few watts than regular refrigerators. I am sure it must be something to do with the extra difficulty of removing the heat from the liquid nitrogen or similar...
Redundancy strategies for mechanical -80C freezers
I was wondering what kind of redundancy strategies are people using for their mechanical -80C freezers? I am aware of the following. Please add if you are doing something different. 1) 1 Backup freezer for every 10 freezers – Empty and maintained at -80C at all times 2) Backup C02...
Safety guidelines for handling cryo vessels of nitrogen
I am looking for any safety guidelines for handling cryogenic vessels of nitrogen indoors and outdoors. I am especially interested in recommendations for area monitors to detect leaks, flow detection devices, etc.
Method to move components in a cryogenic environment
Does anyone know of a method with which to reliably move components in a cryogenic environment? We are interested in moving detectors in a cryogenically cooled (2K) vacuum chamber, which is contained within a larger cryostat/isolation vacuum with thermal shields. As the desired horizontal or vertical displacement is between 10...
