MLI Blankets from Web Industries Improve Commercial Space Offerings

Needs for custom-made, space proven components and systems take on added urgency as launch dates proliferate and space facilities around the world hum with activity. Supply partners like Web Industries (CSA CSM) that offer such components can support space initiatives and help space and satellite companies meet ever-tightening launch deadlines....

Young Professionals 2021

Young Professionals 2021 introduces outstanding young professionals (under 40 years of age) who are doing interesting things in cryogenics and superconductivity and who show promise of making a difference in their fields.

Ability Engineering Technology Providing Remote Purifier Commissioning, Improved Industrial Gas Abilities

Prompted by the pandemic’s “new normal,” South Holland IL-based Ability Engineering Technology (AET, CSA CSM) has adopted a remote commissioning procedure in response to the pandemic’s continuously changing directives. AET has adopted a remote, data-based training approach to improve their commissioning abilities and product line.

Cryogenic Electronics: Part 1

This is the first part of a two-part article about cryogenic electronics, the operation of electronic devices, circuits and systems at temperatures considerably below the “standard” electronics lower limit of −55° C. Alternative names are cryoelectronics, cold electronics and low-temperature electronics. Presented by Dr. Randall Kirschman.

In Memoriam: Brian Dudley

Latest in Defining Cryogenics

Refrigerators and Liquefiers

Two of the most common terms used in cryogenics are “refrigerator” and “liquefier.” These terms describe similar and, as will be seen, in some cases identical components. A refrigerator provides cooling (that is, absorbs heat) at cryogenic temperatures. Refrigerators typically put a working fluid (such as helium) through one of...

Air Separation

Air separation is one of the largest, as well as earliest, industrial applications of cryogenics. In this process, cryogenic temperatures are used to separate air into its constituent gases: nitrogen (78.08%), oxygen (20.95%), argon (0.93%) and carbon dioxide (0.3%). Trace gases such as krypton, neon, xenon and helium total far...

Coefficient of Performance and Figure of Merit

The coefficient of performance (COP) is used to describe the effectiveness of refrigerators, including those operating at cryogenic temperatures. The COP is defined as the amount of heat removed at the cryogenic operating temperature of the refrigerator divided by the amount of work that must be applied to remove the...

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...
