#BlackinPhysics Week Builds Community, Increases Visibility

Walking to his lab one afternoon last year, physicist Charles Brown found his way blocked by a white student who refused to let him into the physics building and demanded to see his ID. A postdoc at the University of California, Berkeley, studying ultracold atoms, Brown says the incident reflects...

RIX Cryocooler Tested, Accepted by US Navy for Aircraft Carrier Use

RIX Industries (CSA CSM) announced in August that it had supplied mission-critical cryocooler technology for shipboard pilot and medical applications onboard the USS Gerald R. Ford (CVN-78). The company designs and manufactured a state-of-the-art liquid and gaseous oxygen generating plant that is now used onboard the ship.

Berkeley Lab Scientists Contribute to New Exploration of Higgs Boson Interactions

Since the discovery of the Higgs boson in 2012 based on data from the ATLAS and CMS experiments at CERN’s Large Hadron Collider, scientists have been gathering new data on the Higgs particle and its associated Higgs field to understand how—and whether—it interacts with specific types of other particles. Released...

NASA’s SOFIA Discovers Water on Sunlit Surface of Moon

Announced on October 26, NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) has confirmed, for the first time, water on the sunlit surface of the Moon. This discovery indicates that water may be distributed across the lunar surface, and not limited to cold, shadowed places.

Quirky Response to Magnetism Presents Quantum Physics Mystery

The search is on to discover new states of matter, and possibly new ways of encoding, manipulating and transporting information. One goal is to harness materials’ quantum properties for communications that go beyond what’s possible with conventional electronics. Topological insulators—materials that act mostly as insulators but carry electric current across...

Instant Systems Promotes Best Practices for Cryogenic Packaging Selection

Elizabeth Beck of Instant Systems (CSA CSM), a leading supplier of cryogenics packaging solutions, outlines the three key attributes to keep in mind when selecting the most suitable flexible packaging for a particular cryogenic application.

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...

Wind Tunnels

Dr. Robert Kilgore The development of the cryogenic wind tunnel is one of many significant breakthroughs in both cryogenics and wind-tunnel technology made during the past millennium. Interest in the development of high-speed commercial and military aircraft resulted in a review of problems of flow simulation in transonic wind tunnels...

History of Cryogenics

From the Fall 1999 issue of Cold Facts magazine Millennium Breakthroughs A variety of CSA members give different perspectives on the past millennium: What were the most significant breakthroughs in cryogenics during the past millennium? Prof. R.G. Scurlock, Kryos Technology, scurlock@soton.ac.uk (“Breakthrough” = way through obstacles — Oxford English Dictionary)...

Cryobiology

Andreas Sputtek Past President Society for Cryobiology sputtek@uke.uni-hamburg.de or http://www.sputtek.de/. The word cryobiology (from the Greek words “cryo” = cold, “bios” = life, and “logos” = science) literally signifies the science of life at low temperatures. In practice, this field comprises the study of any biological material or system (e.g.,...

Cryogenic Insulation

James E. Fesmire Cryogenics Test Laboratory NASA Kennedy Space Center james.e.fesmire@nasa.gov Introduction In today’s world, the use of cryogenics and low-temperature refrigeration is taking a more and more significant role. From the food industry, transportation, energy, and medical applications to the Space Shuttle, cryogenic liquids must be stored, handled, and...
