CERN FCC Study Explores Cooling Requirements For Future Circular Colliders
CERN’s Large Hadron Collider is the world’s most powerful collider with planned operation through the mid 2030s. Therefore, it is timely to design a future collider that could identify physics beyond the standard model and help us explain the open questions about our universe.
CSA Certifies Newly Elected Officers, Directors
CSA board certified results of its 2018 election at the meeting held during the Applied Superconductivity Conference in Seattle.
Physicists Uncover State of Matter in Superconducting Material
A team from Ames Laboratory and the University of Alabama Birmingham has discovered a remarkable new state of matter within an iron pnictide superconductor, revealing a laser-induced formation of collective behaviors that compete with superconductivity around 16 K.
SpaceX Launch System Redesigned, Ready for Testing
SpaceX indicates that a test vehicle for the company’s next-generation launch system could be ready for testing early in 2019. The test hopper will be powered by three of the company’s methane/liquid oxygen engines, units that were "radically redesigned" according to chief executive Elon Musk.
US Cryogenics Lab Critical for Pacific Operations
A US military base in Okinawa includes the only cryogenic facility for the US Air Force in Japan, producing and supplying the oxygen and nitrogen necessary to keep US aircraft in the sky. The unit, however, is also known for saving local lives and making ice cream.

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...

Effect of cryogenic freezing on tone of bell?
I have been making bells for a few years out of Bell Bronze, 87% Copper. Would cryogenic freezing have any effect on the tone of a bell if I had it treated after casting? Your help would be appreciated.
Thermal conductivity of niobium, tantalum, lead, tin
I am interested in the thermal conductivity and other properties of low temperature superconductors. Specifically I am interested in materials like Niobium, Tantalum, Lead and Tin. Would you know of a publication that dealt with thermal properties in general and also gave specific data on these materials?
Could boxes of paper records be freeze-dried?
In the event of a disaster such as a flood, could boxes of paper records be freeze-dried? Could cryogenics help in the recovery efforts?
