US Dept. of Energy approves Lake Charles LNG non-FTA export application

The Department of Energy has conditionally authorized Lake Charles Exports to export domestically produced liquefied natural gas (LNG) to countries that do not have a Free Trade Agreement (FTA) with the United States from the company's terminal in Lake Charles, Louisiana.

Former SSC site now revitalized facility

Twenty years after the closing of the former Superconducting Super Collider, it is now a revitalized facility renovated by Waxahachie chemical manufacturer Magnablend. The Ellis County site improvements were highlighted in a tour the company hosted for US Rep. Joe Barton (R-TX), who was instrumental in bringing the SSC facility...

IARPA releases solicitation for SC research in high-performance computing

US government researchers are asking industry to develop a small computer based on superconducting logic and cryogenic memory that is energy-efficient, scalable, and able to solve interesting problems—particularly those that involve intelligence gathering and analysis.

NIST seeks proposals to establish new center of excellence on advanced materials research

The National Institute of Standards and Technology (NIST) has announced a competition to create an Advanced Materials Center of Excellence to foster interdisciplinary collaborations between NIST researchers and scientists and engineers from academia and industry. The new center will focus on accelerating the discovery and development of advanced materials through...

NASA and Korean space agency discuss space cooperation

NASA Administrator Charles Bolden and the president of the Korea Aerospace Research Institute (KARI), Seung Jo Kim, met in Washington on July 29 to discuss collaboration in aeronautics research and space exploration, including KARI's robotic lunar mission and NASA's asteroid initiative.

Giant magnet completes 3,200-mile trip to Fermilab

On Friday, July 26, a month-long journey came to an end, as the 3200-mile transport of a fragile, 50-foot-wide electromagnet was successfully completed.

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

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...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
