Companies Adapt Cryocooler Technology for New Applications
Cryocoolers are making inroads into commercial applications and are getting closer to our everyday lives. It is well known in the cryogenics community that cryocoolers have been in increasing demand for wider applications.
Researchers Hunting Exoplanets with Superconducting Arrays
The key to revealing the exoplanets tucked away around the universe may just be locked up in the advancement of Microwave Kinetic Inductance Detectors (MKIDs), an array of superconducting detectors made from platinum sillicide and housed in a cryostat at 100 mK.
Cryocoolers, a Brief Overview
Cryocoolers are a type of refrigerator designed to reach cryogenic temperatures. Engineers use the term most often for smaller systems, typically no larger than table-top size, with input powers less than about 20 kW.
2nd International Conference on Cryogenics and Refrigeration Technologies
The city of Bucharest hosted the 2nd International Congress on Cryogenics and Refrigeration Technologies May 7-10, welcoming attendees with delicious food, pleasant parks, numerous museums and plenty of research and conversation.
Columbia Researchers Squeeze Light into Nanoscale Devices and Circuits
Columbia investigators have invented of a novel "home-built" cryogenic near-field optical microscope that has enabled them to directly image, for the first time, the propagation and dynamics of graphene plasmons at variable temperatures down to -250°C.

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...
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?
