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 Electronics
Randall Kirschman, consulting physicist, Mountain View, California ExtElect@gmail.com Cryogenic electronics—the operation of electronic devices, circuits, and systems at cryogenic temperatures—has been a valuable technology for decades. Cryogenic electronics (also referred to as low-temperature electronics, or cold electronics) can be based on semiconductive devices, on superconductive devices, or on a combination...
Particle Physics: High Energy Physics
Cryogenics and High-Energy Physics 1. From symmetry magazine: http://www.symmetrymagazine.org/cms/?pid=1000627: Cryogenics is the study of how materials behave at temperatures near absolute zero. In high-energy particle accelerators, such frigid temperatures reduce the electrical resistance of wires in superconducting magnets, increasing the magnet strength and allowing faster particle acceleration. The same holds...
HTS Degaussing Systems
From the Spring 2009 issue of Cold Facts (Volume 25, Number 2): Thanks to a joint project by the US Navy and a number of industry partners, high temperature superconducting (HTS) technology is now at the heart of an advanced degaussing system aboard the USS Higgins at the naval station...
Magnetic Resonance Imaging
From http://www.superconductors.org: An area where superconductors can perform a life-saving function is in the field of biomagnetism. Doctors need a non-invasive means of determining what’s going on inside the human body. By impinging a strong superconductor-derived magnetic field into the body, hydrogen atoms that exist in the body’s water and...
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.
