CERN FCC Study Explores Cooling Requirements For Future Circular Colliders
CERN’s Large Hadron Collider is the world’s most powerful collider with planned operation through the mid 2030s. Therefore, it is timely to design a future collider that could identify physics beyond the standard model and help us explain the open questions about our universe.
CSA Certifies Newly Elected Officers, Directors
CSA board certified results of its 2018 election at the meeting held during the Applied Superconductivity Conference in Seattle.
Physicists Uncover State of Matter in Superconducting Material
A team from Ames Laboratory and the University of Alabama Birmingham has discovered a remarkable new state of matter within an iron pnictide superconductor, revealing a laser-induced formation of collective behaviors that compete with superconductivity around 16 K.
SpaceX Launch System Redesigned, Ready for Testing
SpaceX indicates that a test vehicle for the company’s next-generation launch system could be ready for testing early in 2019. The test hopper will be powered by three of the company’s methane/liquid oxygen engines, units that were "radically redesigned" according to chief executive Elon Musk.
US Cryogenics Lab Critical for Pacific Operations
A US military base in Okinawa includes the only cryogenic facility for the US Air Force in Japan, producing and supplying the oxygen and nitrogen necessary to keep US aircraft in the sky. The unit, however, is also known for saving local lives and making ice cream.

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...
Refrigeration capacity at 4.5 K for higher temp cryo systems
I would like to know how to calculate the equivalent refrigeration capacity at 4.5 K of a cryogenic system operating at higher temperature.
Need help with calculating flow rate
I have to maintain a certain mass (some tons) at 100 K by circulating in it GHe (through apposite channels). How can I calculate the flow rate needed? I suppose that the delta T (T inlet and T outlet) and the heat load on the mass are necessary. Knowing the...
What do cryogenics companies do about liability insurance?
What do cryogenics companies do about liability insurance? Is there a special type for cryogenics?
License requirements for storage and transport of cryogenic materials
Are you aware of permitting or license requirements (other than local city or town) needed for the storage or transportation of cryogenic materials?
