Meyer Tool contributes to Alpha Project
Professors S. Y. Lee and Paul Sokol of the Indiana University Center for Exploration of Energy and Matter (IUCEEM) are currently leading the design effort of a multipurpose electron accelerator called the Alpha Project (Advanced Electron-Photon Facility), which will be operated under a joint collaboration between Crane Naval Surface Warfare...
LHC sets record as highest energy particle accelerator
On March 19, the LHC set yet another energy record as it ramped up to circulate two 3.5 TeV proton beams for the first time.
GE to expand access of MRI systems to underdeveloped regions
GE Global Research has been awarded a four-year, $3.27 million award from the National Institutes of Health (NIH) for new magnet technology that will cut back on the costs and inconveniences of current MRI systems.
BNL’s RHIC detects exotic antimatter
From http://www.bnl.gov: An international team of scientists studying high-energy collisions of gold ions at the Relativistic Heavy Ion Collider (RHIC), a 2.4-mile-circumference particle accelerator located at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, has published evidence of the most massive antinucleus discovered to date.
Hypres Figure of Merit for Multi-Stage Cryocoolers
In the Winter 2010 issue of Cold Facts, an article was featured entitled "Hypres: Progress in SC RF for Telecommunications." The article mentions that Hypres has developed a figure of merit (FoM) that allows them to compare cryocoolers with different stages for their applications.

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...
Air Separation and Liquefaction

You are encouraged to read Cryo Central’s History...
Bose-Einstein Condensate
A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...
Cold Technology for Pest Control
While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...
Cryogenic Finishing
The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...
Convert PSI or Torr to Degrees Kelvin?
When using helium vapor bulbs under 30K, what is the formula to convert from PSI or Torr to degrees Kelvin?
Searching for a company to make a specific kind of cryogenic chamber
I am writing a proposal to do some deep space simulations of mechanical vibrations at cryogenic temperatures. For the research, I will need to obtain a chamber that has a space of approximately 1700 cubic inches (or a 12in. cube) that also has an optical viewing window.
