ASC 2020 Is Ongoing

The organizers of the 2020 Applied Superconductivity Conference are presenting a completely virtual conference through November 7, 2020. The two-week format aims to accommodate international attendance and make viewing presentations convenient and easy to experience. https://ascinc.org/registration/

ITER Prepares Thermal Shield: The Ultimate Heat Barrier

In ITER's French Assembly Hall environment, a strange component shines like a freshly polished mirror. Lying horizontal, it looks like a giant's tiara; when upended to the vertical position and paired to its missing half, it will fit between the vacuum vessel and magnetic system of the machine and act...

#BlackinPhysics Week Builds Community, Increases Visibility

Walking to his lab one afternoon last year, physicist Charles Brown found his way blocked by a white student who refused to let him into the physics building and demanded to see his ID. A postdoc at the University of California, Berkeley, studying ultracold atoms, Brown says the incident reflects...

RIX Cryocooler Tested, Accepted by US Navy for Aircraft Carrier Use

RIX Industries (CSA CSM) announced in August that it had supplied mission-critical cryocooler technology for shipboard pilot and medical applications onboard the USS Gerald R. Ford (CVN-78). The company designs and manufactured a state-of-the-art liquid and gaseous oxygen generating plant that is now used onboard the ship.

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

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...

Getter materials to absorb out gassed materials?

Here’s one for the scientists: We would like to sell vacuum insulated pipe for high temperature fluid applications. Are there any good getter materials that we can place in the vacuum space of our VJP to absorb outgassed materials at elevated temperatures?
