On April 1, the dome of the Mayall Telescope in Tucson AZ opened to the night sky, and starlight poured through the assembly of six large lenses that were carefully packaged and aligned for a new instrument that will launch later this year.
Demaco Holland BV (CSA CSM) is lending its cryogenic expertise to the development of a rotor cryostat for the Advanced Supeconducting Motor Experimental Demonstrator, which will develop, build and test the first fully superconductive motor for aerospace applications.
CSA celebrates women in cryogenics and superconductivity. In this feature, six women in positions across the industry discuss current projects, how they entered the field and their thoughts on attracting more women to the profession.
The definition of the kelvin (K)—the temperature unit of the International System of Units (SI), has been given a radically new definition. This redefinition was the result of 60 nations’ unanimous vote to revise the SI in November 2018.
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...
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 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...

You are encouraged to read Cryo Central’s History...
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...
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...
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...
I am a final year Physics Undergraduate at the University of Cambridge (UK). As a part of one of my courses this year, I have been asked to investigate the use of hydrophobic surfaces in cryogenics.
