SGD Productions releases safety video for compressed gases, cryo liquids
SGD Productions, LLC. has introduced a new safety video entitled, "The Control and Safe Handling of Compressed Gases."
Garbincius reports on International Workshop on Linear Colliders (IWLC2010)
From ILC Newsline, October 28, Director's Corner with Peter H. Garbincius, Global Design Effort Cost Manager: The International Linear Collider community has typically held major meetings twice a year where the accelerator and physics and detector people come together, both to review the status of and make progress in their...
Oddone warns of a “period of uncertainty”
From Fermilab Today's November 9 Director's Corner: With the changes in the Congress following the mid-term election last week, we have an increased sense of uncertainty regarding our funding for FY 2011 and FY 2012, and hence greater uncertainties for the programs we are embarked on.

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...
Convert PSI or Torr to Degrees Kelvin?
When using helium vapor bulbs under 30K, what is the formula to convert from PSI or Torr to degrees Kelvin?
Searching for a company to make a specific kind of cryogenic chamber
I am writing a proposal to do some deep space simulations of mechanical vibrations at cryogenic temperatures. For the research, I will need to obtain a chamber that has a space of approximately 1700 cubic inches (or a 12in. cube) that also has an optical viewing window.
