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.
Boeing 777 and problems with ice in fuel
In January 2008 British Airways flight BA038, a Boeing 777 that departed from Beijing, crashed while on final approach to London Heathrow airport after both its jet engines lost power, a condition known as roll-back. Dr. Ralph G.Scurlock explains how the UK and US Air Accident Investigation authorities, together with...

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...
Cryogenic Treatment of Materials
F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...
Cryogenics in Space
Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

Liquefied Natural Gas
Liquefied Natural Gas as it relates to the Field of Cryogenics John W. Bonn VJ Systems, LLC johnbonn@vjsystems-lic.com Today the world is looking for a cleaner fuel and Liquefied Natural Gas (LNG) plays a large part in achieving this goal. LNG in a liquid form is at -162°C (-259°F) and...
Thermal shock on steel cylinder when dropped into liquid nitrogen
We are a research team at the University of South Florida, studying the “thermal shock” on a steel cylinder when it is dropped into liquid nitrogen. We want to make sure that the thermocouple does not get influenced by the surrounding LN2. Any advice?
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?
Data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K.
I am looking for data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K. I would appreciate it if someone could give me some hints on where to find it.
