European XFEL underground construction completed

An important milestone was reached at Germany’s largest science construction site: The underground civil engineering work for the X-ray laser European XFEL has been completed, and underground construction is almost finished.

Researchers create microscale pumps to evacuate tiny vacuum chambers

DARPA-funded researchers recently demonstrated the world’s smallest vacuum pumps. This breakthrough technology may create new national security applications for electronics and sensors that require a vacuum: highly sensitive gas analyzers that can detect a chemical or biological attack, extremely accurate laser-cooled chip-scale atomic clocks and microscale vacuum tubes.

Canadian National Railway orders four LNG tenders from Westport

Westport Innovations Inc. has announced the launch of a liquefied natural gas (LNG) tender product solution with an order for four tenders from Canadian National Railway.

Air Products introduces new microsite

Air Products has launched a new microsite that features the company’s advanced cryogenic technologies, which use the unique properties of liquid nitrogen to provide an economical, simple way of cooling for a variety of applications.

Air Liquide announces new organization and leadership team in US

Air Liquide has announced a realignment of its executive management team in the US in conjunction with Air Liquide Group's recently introduced strategic organization and growth plan.

European Commission and CERN support major research facility in the Middle East

The European Commission and CERN agreed on May 28 to support the construction of SESAME (Synchrotron-light for Experimental Science and Applications in the Middle East), one of the most ambitious research facilities in the Middle East.

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...
