Neutrinos can deliver both full-on hits and “glancing blows”

In what they call a “weird little corner” of the already weird world of neutrinos, physicists have found evidence that neutrinos might be involved in a surprising reaction: interacting with a nucleus and leaving it basically untouched, inflicting no more than a glancing blow.

Accelerator-powered carbon dating

Accelerator mass spectrometry, an accelerator-driven form of carbon dating that requires only a tiny sample of the material, is advancing everything from archaeology to personalized medicine.

First LHC magnets prepped for restart

One-eighth of the Large Hadron Collider (LHC) dipole magnets have reached the energy they'll need to operate in 2015. Engineers at CERN powered 154 superconducting magnets to a current of around 11,000 amps. This is about 1,000 times greater than an average household appliance and is required to make the...

Save the Date for the 2015 Space Cryogenics Workshop

NASA Glenn Research Center announces the 2015 Space Cryogenics Workshop (SCW), a division of the Cryogenic Society of America. All aspects of space cryogenics will be represented, with an emphasis on work related to previous missions as well as future research.

CSA Board Certifies Newly Elected Directors

At the August 14 CSA Board meeting held during the Applied Superconductivity Conference in Charlotte NC, the four directors recently elected by the society's membership were certified.

Superconductivity: Will It Be Coming in from the Cold?

Dr. Paul Michael Grant assesses the application of superconductivity within the electric power sector, asking, "Is there a 'hot track' upward for both applications of today's superconductors and future transition temperatures beyond 200K as well?"

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...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...
