2015 Nobel Prize in Physics awarded to neutrino oscillation experimenters

The Royal Swedish Academy of Sciences on October 6 awarded the 2015 Nobel Prize in Physics to Takaaki Kajita and Arthur B. McDonald in recognition of key contributions each made to experiments demonstrating neutrino oscillations. Physicists struggled for decades prior to Kajita's and McDonald's experiments to explain why up to...

CONCOA opens new facility in Taiwan

CONCOA has opened its second marketing facility and product support center in the Pacific region, an area the firm sees as strategic for investment and trade. Located in the greater Taipei area, the new facility supports business partners in China, Hong Kong, Japan, Macao, South Korea and Taiwan.

ITER superconductor production nears completion

The single largest superconductor procurement in industrial history is drawing to a successful close. An eight-year campaign to produce the superconductors for ITER's powerful magnet systems is in its final stages, with nearly 70 percent of the conductor units lengths accepted by the ITER Organization.

Fermilab powers up electromagnet dormant for a decade

Fermilab announced September 23 that scientists there have successfully brought a fragile, expensive and complex 17-ton electromagnet back to life, cooling it down to -450°F and then powering it up. The ring is the centerpiece of an experiment to probe the mysteries of the universe with subatomic particles called muons....

Magnolia LNG awards $40 million for liquefaction equipment

Magnolia LNG, a subsidiary company of Liquefied Natural Gas Limited, announced on September 22 that it had awarded $40 million in contracts to Chart Industries, Inc., for a mid-scale LNG project at Lake Charles LA. Chart will initially deliver two identical trains, each with a nominal LNG production capacity of...

DOE posts new Women@Energy profiles

The Department of Energy recently updated its Women@Energy webpage to include new profiles on researchers working at its national laboratories. There are now over 250 profiles on the page, each celebrating a woman who works in a STEM field. The new profiles include female scientists working at Jefferson Lab (CSM)...

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 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...

TS diagram for helium

Where can I obtain a really big, nice TS diagram for helium ?

Reliability and mounting of electronic substrates at low temperatures

I am currently working on the design of a focal plane assembly to be implemented on a small satellite (4 EMCCD detectors) to be operated at -80°C (which is not really cryogenic and likely still considered boiling hot for most of you :-). As it is passively cooled, the assembly...

Are 3D drawings included in the sale of a cryogenic plant?

I have a question concerning the 3D drawings of a cryogenic plant. The integration of the 3D drawings of a plant with the 3D main model of a new laboratory or a new facility can be a complex work that takes a lot of time. I would like to know...

Looking for a source of LOX impact testing to ASTM D2512

I have been looking for a source of LOX impact testing to ASTM D2512. I am aware of NASA and White Sands, but am looking for a commercial entity doing the work. No luck so far, even calling a lot of the folks on the CSA website. Any referrals will...
