Sandwiched Graphene Adopts Andreev States

MIT physicists have found that a flake of graphene, when sandwiched between two superconducting materials, can inherit some of those materials’ superconducting qualities. The electronic state of the graphene changes dramatically here, even at its center, as the particles pair up in Andreev states—a fundamental electronic configuration that allows a...

Auguste and Taylor-Wharton Ink New Distribution Deal

Auguste Cryogenics has signed a long-term liquid cylinder distribution agreement with Taylor-Wharton, becoming the exclusive distributor in Europe, Russia and Israel for Taylor-Wharton’s extensive line of gas and liquid withdrawal cylinders.

Researchers Develop Circuit Refrigerator for Quantum Computers

Cooling has proven to be a major concern for engineers developing quantum computers, but now a research team at Finland's Aalto University says it has invented a quantum circuit refrigerator that could reduce errors in quantum computing. Quantum computers differ from the computers that we use in that, instead of...

Ball Aerospace Developing Cryostat for GUSTO

NASA has chosen Ball Aerospace to design and build a cryostat for its Galactic/Extragalactic Ultralong Duration Balloon (ULDB) Spectroscopic Terahertz Observatory mission, or GUSTO. The mission, led by the University of Arizona, will measure emissions from the interstellar medium, helping scientists to determine the life cycle of interstellar gas in...

Nikkiso Acquires Cryogenic Industries

Nikkiso Co., Ltd. has announced its acquisition of Cryogenic Industries (CSA CSM), a group of product and service companies supporting both liquefaction and separation plants for air gases and small-scale plants for LNG liquefaction. The deal is worth an estimated $440 million and is expected to close in August.

CERN Celebrates Linac 4 Completion

The European Organization for Nuclear Research (CERN) celebrated the completion of its Linac 4 during a ceremony on May 9. The new accelerator is expected to allow the Large Hadron Collider (LHC) to reach higher luminosity by 2021. The machine is almost 90 meters long, sits 12 meters below the...

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...

Designing a liquid oxygen bath

I’m designing a Liquid Oxygen Bath to place composite coupons in the bath and soak 96 samples for intervals of 8 hours, 24 hours, 7 days, 21 days, 42 days, 62 days and 90 days.

Metallic Salts Normally Used to Produce Ultra-Low Temperatures?

Regarding the method known as the Adiabatic Demagnetization of Paramagnetic Salts: What metallic salts are normally used to produce the ultra-low temperatures used for near-absolute-zero cryogenic research? Which salts are the most efficient? Which make the best cooling agents? And which are used most commonly by physicists? I am looking...

Specs and info on turbo expanders

I am a fourth year chemical engineering student doing a design project for the liquefaction of natural gas to DME and we are using a turbo expansion unit. I was wondering whether you would send me some specs and any additional information on turbo expanders that I could use as...
