Education in Cryogenics, Superconductivity: Some Updates

The following are some recent updates and additions to the information offered at CSA’s website about educational opportunities in cryogenics and superconductivity, both in classrooms and nontraditional settings, in the US and around the world.

Registration Open for ‘Foundations of Cryocoolers’ Short Course at ICC18

Registration is now open for the “Foundations of Cryocoolers” short course to be held on Monday, June 9, 2014, right before the 18th International Cryocoolers Conference (ICC18). The conference will be held June 9-12 at Syracuse University, Syracuse NY. Conference Chairman is Rich Dausman of Cryomech, Inc. and Co-Chair is...

US Gov’t Shutdown Affects Cryo, Superconductivity

In October, it would have been hard to miss the news of the 16-day US federal government shutdown, even for those located outside of the United States. The shutdown came as a result of Congress’ inability to enact legislation appropriating funds for fiscal year 2014 or to agree on a...

Use of fiberglass in the LNG market

I am doing a bit of market research on the use of fiberglass in the LNG market. What is the type and weave of fiberglass used in LNG manufacturing? Is it used aesthetically or is there an actual technical purpose for the fiberglass, such as insulation? Can you name the...

Stirling Cryocoolers for the LNG Market

Interest in use of Stirling cryogenerators (cryocoolers) for liquefied natural gas (LNG) applications has grown with the increasing worldwide demand for the gas. Cryogenerators act as cold heat exchangers which can directly reliquefy methane gas. They are typically used for direct liquefaction of an LNG stream, e.g. that produced from...

Minimizing Eddy Currents in Superinsulation

RUAG's study investigated various processes to structure metallic coatings to develop a better product. The aim was to retain the high reflectivity provided by the aluminum and to reduce the eddy currents to a level acceptable for different application

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

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.

Cryogenic cooling as possible treatment of aluminum parts for semiconductor industry

I’m interested in cryogenic cooling as a possible treatment of aluminum parts for the semiconductor industry.
