At DOE, body blows to fusion, nuclear physics and particle physics
Overall, the 2013 budget numbers for the Department of Energy's (DOE's) Office of Science, the single largest funder of physical sciences research in the United States, look reasonably good. The office would see its budget climb by 2.4% to $4.992 billion. Three of the office's six major research programs, however,...
CERN experiment makes spectroscopic measurement of antihydrogen
In a paper published online on March 7 by the journal Nature, the ALPHA collaboration at CERN reports an important milestone on the way to measuring the properties of antimatter atoms.
Fab team scales up production of dark matter detectors
It's one thing to design and build a brand-new piece of technology, to test it and tune it until it works just right. It's an entirely different matter to take that one-of-a-kind instrument and mass-produce it.
IBM captures first-ever image of single-molecule charge distribution
IBM scientists were recently able to measure for the first time how charge is distributed within a single molecule.
Error undoes faster-than-light neutrino results
It appears that the faster-than-light neutrino results, announced last September by the OPERA collaboration in Italy, was due to a mistake after all. A bad connection between a GPS unit and a computer may be to blame.

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...
Any experience with G-10 in an extremely cold environment?
I have a cryostat with closed cycle cryocooler attached. The case is aluminum with a G-10 spacer between the case and a stainless steel bellows that supports the cryocooler.
Cryogenic sealant for LNG fueled buses?
Where can I find a cryogenic sealant for my LNG fueled buses?
Material/gel/epoxy to transfer cold temperature of a cryo-box to a test article
I’m on the hunt for a material/gel/epoxy that will transfer the cold temperature of a cryo-box to a test article. The cryo-box is curved and the test article is at the same curvature. I’m looking for something to put between them to make the surface of the test article as...
Manufacture of brazed aluminum heat exchangers: need consultant
I’m seeking a consultant with experience in the manufacture of brazed aluminum heat exchangers for cryogenic applications. Is there anyone you could recommend to me?
