Physicists, medical industry team up to build advanced cancer therapy accelerator
A new collaboration between the U.S. Department of Energy’s Brookhaven National Laboratory and Best Medical International (BMI) aims to design one of the most dynamic and effective cancer therapy devices in the world.
Fermilab’s SRF program incorporates old equipment into new designs
Some people make coffee coasters out of old newspapers or lawn ornaments out of rusty shovels. Fermilab is building a particle accelerator that employs $28 million of recycled equipment and material.
Academics rallying to boycott Elsevier
Over 4,000 scientists have signed an online petition in protest over the pricing and distribution policies of Elsevier, a publisher which sells over 2,000 academic journals along with 20,000 other books. Many of the signatories are distinguished academics at such institutions as Harvard, Yale, McGill, Cambridge and Oxford. They promise...
MSU Board approves next step of FRIB project
The Michigan State University Board of Trustees has given its approval to the next step in the development of the Facility for Rare Isotope Beams, a world-class nuclear research facility that will attract scientists from all over the world to East Lansing while creating more than $1 billion in economic...
Scientist recounts superconductivity discovery
Like many young men from Alabama, Jim Ashburn's path to fame involved football, good timing, a fair dose of serendipity (or good luck, if you prefer), timely coaching and a strong team. Ashburn's path also included a love of science, especially mathematics.

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

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...
Looking for manufacturers of cryogenic dewars with infrared detectors (long wave)
We are looking for manufacturers of cryogenic dewars with infrared detectors (long wave). We need these dewars for repairing infrared systems (thermographic systems) and we cannot find such glass dewars. Do you know any manufacturers’ addresses?
Manufacturers of cryogenic regenerator lead spheres?
Would you please suggest a few manufacturers that produce cryogenic regenerator lead spheres? The size we need is 0.15mm-0.2mm. I don’t have a lot of ideas for where to go to purchase them.
Assistance with resolving a sealing problem?
We are fabricating piping components for refrigeration service. These components must be leak checked at 15 bar (218 psig). We are using a gas test media that is 25% helium and experiencing difficulty on maintaining a seal on the flanged connections. Do you know anyone or any references that could...
Cryogenic data on leather and nomex
Could anyone please help me out with the following cryogenics data: Leather — mechanical properties at 77 K or lower Nomex — thermal conductivity @ 4 to 50 K I lost the data I had some time ago and although this should be easily accessible, I can’t find any reference...
