Fermilab director announces voluntary separation program
Pier Oddone, Director at Fermi National Accelerator Laboratory, announced on June 16 that the lab would begin a self-select voluntary separation program (SSVSP) in order to reduce staff by 100.
CSA Corporate Members win R&D awards
R&D Magazine recently announced its "R&D 100" winners for 2011. Several CSA Corporate Sustaining Members were among the winners: Argonne National Laboratory, Brooks Automation, Inc., Oak Ridge National Laboratory and Sierra Lobo. Read the list of winners on the R&D website.
NIST scientist details new method for making thinner, more flexible HTS cables
NIST scientist Danko van der Laan explains details of his invention of a method to make HTS cables that are thinner and more flexible than ever before. The superconducting material used to make the cables is a high-temperature superconducting "coated conductor" that consists of a 50-micron-thick Hastelloy substrate, coated with...
Tributes to Dr. Klaus Timmerhaus
Dr. Klaus D. Timmerhaus, who passed away February 11, 2011, was well-known in the cryogenics community for a number of accomplishments, including his involvement in the Cryogenic Engineering Conference and for serving as founding editor of the publication “Advances in Cryogenic Engineering,” which he edited from 1954 to 1980.
LHC experiments reach data milestone for 2011
CERN press release, June 17: Today at around 10:50 CEST, the amount of data accumulated by LHC experiments ATLAS and CMS clicked over from 0.999 to 1 inverse femtobarn, signaling an important milestone in the experiments' quest for new physics.

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...
Effect of cryogenic freezing on tone of bell?
I have been making bells for a few years out of Bell Bronze, 87% Copper. Would cryogenic freezing have any effect on the tone of a bell if I had it treated after casting? Your help would be appreciated.
Thermal conductivity of niobium, tantalum, lead, tin
I am interested in the thermal conductivity and other properties of low temperature superconductors. Specifically I am interested in materials like Niobium, Tantalum, Lead and Tin. Would you know of a publication that dealt with thermal properties in general and also gave specific data on these materials?
Could boxes of paper records be freeze-dried?
In the event of a disaster such as a flood, could boxes of paper records be freeze-dried? Could cryogenics help in the recovery efforts?
Where can the cryogenic insulator trade be studied?
I have been searching for information regarding the training of cryogenic insulators and have not been able to find any information in North America.
