Turkey to build its first accelerator facility

From symmetry breaking, September 3, 2009: Over the last ten years, Turkish physicists have been working diligently to build a national accelerator center, which would serve as a core science facility and offer increased opportunities for Turkish students.

AMSC India to serve India’s wind energy & power grid markets

American Superconductor Corporation announced today that it has formed AMSC India to serve India's ever-expanding wind energy and power grid markets.

Recovery Act to fund testing and development of SRF cavities

From Fermilab Today, September 4, 2009: In August, the Department of Energy announced that the American Recovery and Reinvestment Act will provide Fermilab with $52.7 million to test and develop superconducting radio frequency cavities, a key technology for next-generation accelerators and the future of particle physics.

Fermilab participates in final Science Chicago Labfest

On Friday, August 21, Fermilab volunteers, docents and Education Office staffers collaborated to make physics fun and accessible at Labfest, a series of outdoor summer science fairs taking place throughout the Chicagoland area.

Recovery Act funds go to test bismuth-based material

The Very High Field Superconducting Magnet Collaboration will soon be using $2 million in Recovery Act funds to test BCCO2212, a bismuth-based material that may allow scientists to create high-field superconducting magnets able to acheive twice the strength of existing magnets.

Chart Energy & Chemicals signs agreement for LNG opportunities

Chart Energy and Chemicals, a wholly-owned subsidiary of Chart Industries, has signed a joint agreement with Toyo Engineering Corporation (TOYO) of Japan to jointly pursue certain mid-scale liquefied natural gas (LNG) opportunities.

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...

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...
