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.

Regenerators
Regenerators or regenerative heat exchangers are a key component of cryocoolers such as pulse tube cryocoolers (Cold Facts, August 2014). Regenerator performance greatly affects the coefficient of performance of cryocoolers. Improvements in regenerator design and, in particular, regenerator materials have been an important factor in the improvement of the performance...
Pulse Tube Cryocoolers
The development of pulse tube cryocoolers has been a significant topic of research and development over the past 20 or so years. Pulse tube cryocoolers have a number of advantages over other types of cryocoolers and are now available commercially. In order to understand pulse tube cryocoolers, it’s best to...
Thermal Expansion
Thermal expansion refers to the change in size (length or volume) that a material undergoes as its temperature changes. In cryogenic systems this effect can be quite large and must be allowed for in the design. In isotropic materials, which include most engineering materials, the thermal expansion is the same...
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...
Cryogenic processing for medical equipment, mining industry
Greetings from Australia. I am looking for a company that I might contact that has any experience or has done any research into cryogenic processing for medical equipment, in particular, joint prosthesis.
