NASA Goddard Hosts Young Women for STEM Girls Night In
Late on a Friday night, 40 high school girls arrived at NASA’s Goddard Space Flight Center in Greenbelt MD for a STEM-themed sleepover, ready to learn about careers in science, technology, engineering and math.
Dr. Roger W. Boom 1923-2018
It is with great regret that we report the death of Dr. Roger W. Boom, emeritus professor from the University of Wisconsin and mentor and inspiration to a great many leaders in the fields of cryogenic engineering and superconductivity.
Cryogenics in Medicine and Biology
The field of cryogenics has been connected with medical applications since its inception, and what follows is a historical review of some of the major applications within medicine where the term cryogenic is used in a specific manner.
DH Industries Contributes To Successful Launch of LNG Barge
The successful completion and delivery of Clean Jacksonville was announced in August, including information on the involvement of CSA member DH Industries BV.
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.

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
by Nils Tellier, PE, President, EPSIM Corporation (CSA CSM) nils@epsim.us All illustrations courtesy EPSIM Corporation Background History of Air Separation and Liquefaction This section builds on a rich history of methods to develop deep refrigeration and cryogenic liquefaction during the 19th Century. 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...
Information on how the emissivity of the panel changes with air fouling?
I work at a facility with a large thermal vacuum chamber. We are using both nitrogen and helium shrouds.
In search of a calculation for designing a cryostat
I am a final year physics student at the University of Birmingham, and as part of a group I am currently designing a cryostat. One of the calculations I need to make (very soon!) is how much heat will be conducted down the walls. All information I have found so...
Safety of ethylene glycol and pressurized oxygen
We are reviewing the product design of liquid filled differential level gauges and want to insure that they meet the industry requirements. The former license owner had authorized that a fill fluid of ethylene glycol (68%) and distilled water (32%) could be used for oxygen service up to 500 psi....
Heat flux in case of vacuum loss on cryogenic surfaces?
Is there anyone who has information about the heat flux in case of vacuum loss on cryogenic surfaces?
