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.

Science Publication Recommends the Physics Books of 2018

Symmetry writer Mike Perricone presented readers with his annual compilation of popular science books related to particle physics and astrophysics. The list includes more than ten suggestions, including "Particle Physics Brick by Brick: Atomic and Subatomic Physics Explained...in LEGO," by Dr. Ben Still.

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...

Magnets

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. Particle physics uses accelerators to recreate the conditions of the early universe in an attempt to piece together the complex puzzle of how we got to where we are today. These huge machines are used...

Energy Storage

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. With power lines increasingly congested and prone to instability, strategic injection of brief bursts of real power can play a crucial role in maintaining grid reliability. Small-scale Superconducting Magnetic Energy Storage (SMES) systems, based on...

Astronomy

ASTRONOMY IN SPACE by Peter V. Mason, retired, Jet Propulsion Laboratory, and Visiting Associate, California Institute of Technology. Pmason@alumni.caltech.edu In thinking about the reasons to perform astronomy in space, we first consider the effect of the earth’s atmosphere. On a scale of decreasing energy, gamma rays, cosmic rays, X-rays and...

Cryocoolers

What is a Cryocooler? A mechanism that can extract heat from an object (cooler) and by doing so draw its temperature down below approximately 150 Kelvin (cryo). — (Courtesy Dr. Willy Gully) What is the difference between a Cryocooler and a Cryostat? A cryostat is any device designed to maintain...

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?
