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...

Transfer Lines
Transfer lines may in some real sense be thought of as the cryogenic fluid analogy of current leads. While current leads carry electrical power to where it’s required in a cryogenic system, transfer lines do the same with cryogenic fluids. Transfer lines range in complexity from very simple U-tubes containing...
Zero Boiloff
Zero Boil Off cryostats are those that contain liquid cryogens but are designed to eliminate or vastly reduce the boil off of the liquid. These cryostats combine some of the advantages of Cryogen-Free systems (e.g. ease of use and long operational lifetime) with the advantages associated with a reservoir of liquid...
Cryomodule
Cryomodule is a term that is most commonly used to refer to cryostats that contain superconducting radio frequency (SRF) cavities. Such cavities are used to accelerate charged particle beams and are a major component of modern particle accelerators. Using the term cryomodule to refer to cryostats containing SRF cavities appears...
Cryogenics in Space
Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

Liquefied Natural Gas
Liquefied Natural Gas as it relates to the Field of Cryogenics John W. Bonn VJ Systems, LLC johnbonn@vjsystems-lic.com Today the world is looking for a cleaner fuel and Liquefied Natural Gas (LNG) plays a large part in achieving this goal. LNG in a liquid form is at -162°C (-259°F) and...
Food Processing
Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...
An Issue of Pressure and Flow Rate in a Supply Tank
Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...
Using MLI on VJ Line Joints or Cryo Storage Tanks
When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
Separated layers of ice over a pipe
I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
