Liquid Hydrogen
Hydrogen becomes a liquid at 20K and 1 bar. Liquid hydrogen (LH2) is an important substance in industry, transportation and research. Industrial uses of hydrogen include applications in the electronics, glass, chemical and metal processing fields. In these applications, the hydrogen is generally used as a room temperature gas but...
Superconducting Radiofrequency Cavities
Superconducting radio frequency (SRF) cavities represent an important application of cryogenics and superconductivity. SRF cavities are a technology for accelerating charged particle beams via the transfer of radiofrequency (RF) energy to the beams via resonant structures. As such, they are frequently found in large particle accelerators used for scientific research....
Thermal Radiation Shields
Actively cooled thermal radiation shields are a common feature of cryostats whose lowest temperature is less than 77K. These shields, which typically operate at temperatures between that of LN2 and 40K, block thermal radiation from higher temperatures from reaching lower temperature cryogenic components or fluids. Since the heat radiated from...

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...
What is the temperature range of cryogenics?
Could you please tell me what is the temperature range of cryogenics? In other words, is -100°F considered cryogenic, or does it start lower? Could I expect to see some extended life in D2 stamping dies? What would the recipe be to achieve the desired results using cryogenics?
Any suggestions for a company producing "secured" heat exchangers?
I am looking for a company producing “secured” heat exchangers to work at a minimum temperature of -45 C on a cooling system for electronics.
