Physicists, medical industry team up to build advanced cancer therapy accelerator
A new collaboration between the U.S. Department of Energy’s Brookhaven National Laboratory and Best Medical International (BMI) aims to design one of the most dynamic and effective cancer therapy devices in the world.
Fermilab’s SRF program incorporates old equipment into new designs
Some people make coffee coasters out of old newspapers or lawn ornaments out of rusty shovels. Fermilab is building a particle accelerator that employs $28 million of recycled equipment and material.
Academics rallying to boycott Elsevier
Over 4,000 scientists have signed an online petition in protest over the pricing and distribution policies of Elsevier, a publisher which sells over 2,000 academic journals along with 20,000 other books. Many of the signatories are distinguished academics at such institutions as Harvard, Yale, McGill, Cambridge and Oxford. They promise...
MSU Board approves next step of FRIB project
The Michigan State University Board of Trustees has given its approval to the next step in the development of the Facility for Rare Isotope Beams, a world-class nuclear research facility that will attract scientists from all over the world to East Lansing while creating more than $1 billion in economic...
Scientist recounts superconductivity discovery
Like many young men from Alabama, Jim Ashburn's path to fame involved football, good timing, a fair dose of serendipity (or good luck, if you prefer), timely coaching and a strong team. Ashburn's path also included a love of science, especially mathematics.

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...
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...
Cryogenic Treatment of Materials
F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...
Looking for process to freeze large volumes of plastics and rubber
I’m looking for a process to freeze large volumes of plastics and rubber prior to submitting this mass of material to a grinding process that reduces it to a powder. Any thoughts? Any known processes which I can visit? Any known technologies? Can you refer me to other resources for...
Sealant Adhesive KAE 89?
Can you give me contact details for the manufacturer of a “sealant Adhesive” KAE 89? It is a vapor stop, used on insulation covering LNG carrying conduits. This is a suggested alternative to Foster 90-66. Do you have details of any other alternative products for this application?
Data for thermal conductivity for phenoloc high pressure laminate NEMA CE grade
Can you provide data or information on how to obtain data for thermal conductivity for phenolic high pressure laminate NEMA CE grade, at low temperatures (4 Kelvin to 100 Kelvin)?
Definition or max temp which defines “cryogenic”?
Please help me with a definition: I am calculating material and fabrication costs for a quote for a hydrocarbon meter station.
