Towards Cryogen-Free SRF Particle Accelerators
Particle accelerators have been essential tools of particle physics since initial development in the early twentieth century, with commercial applications soon following each successive advancement.
FDA Suggests Avoidance of Food Products Made with Point of Sale Liquid Nitrogen
The US Food and Drug Administration alerts consumers and retailers of the potential for serious injury from eating, drinking or handling food products prepared by adding liquid nitrogen at the point of sale, immediately before consumption.
New Editors Named for International Cryogenics Monograph Series
The Springer publishing company recently named Dr. Sangkwon Jeong and Dr. John Weisend II as new editors for its International Cryogenics Monograph Series. The ICMS series was first established in the early 1960s and has provided a forum for active researchers to report on past developments and present work in...
TRIUMF Celebrates New Five-Year Plan
The scientific community at TRIUMF (CSA CSM) recently gathered at its Advanced Rare Isotope Laboratory to celebrate the new Five-Year Plan for 2020-2025. It defines both the vision and mission for Canada's particle accelerator center, communicating the lab’s goals and strategies while laying out an action plan for the specified...
Lockheed Martin Reveals Human Lunar Lander Concept
Lockheed Martin revealed its concept for a crewed lunar lander during the International Astronautical Congress (IAC) in Bremen, Germany, showcasing how the reusable lander would align with NASA's lunar Gateway and future Mars missions.

Refrigerators and Liquefiers
Two of the most common terms used in cryogenics are “refrigerator” and “liquefier.” These terms describe similar and, as will be seen, in some cases identical components. A refrigerator provides cooling (that is, absorbs heat) at cryogenic temperatures. Refrigerators typically put a working fluid (such as helium) through one of...
Air Separation
Air separation is one of the largest, as well as earliest, industrial applications of cryogenics. In this process, cryogenic temperatures are used to separate air into its constituent gases: nitrogen (78.08%), oxygen (20.95%), argon (0.93%) and carbon dioxide (0.3%). Trace gases such as krypton, neon, xenon and helium total far...
Coefficient of Performance and Figure of Merit
The coefficient of performance (COP) is used to describe the effectiveness of refrigerators, including those operating at cryogenic temperatures. The COP is defined as the amount of heat removed at the cryogenic operating temperature of the refrigerator divided by the amount of work that must be applied to remove the...
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...
In need of books to start a cryogenic engineering department
My company is going to create a cryogenic engineering department and we need some books in order to facilitate this project. This is the kind of information we would like to obtain from the books: 1- Calculations for determining the storage facilities, such as storage tanks, pumps, compressors, etc. 2-...
Having some difficulty with the design of a cryogenic pressure vessel
I am a graduate student in the Dept. of Mechanical Engineering at West Virginia University. As a part of my research, I’m doing a case study of design of a Cryogenic Pressure Vessel. I’m facing a little difficulty in the process, and would be very grateful to you if you...
