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.

Helium II
Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...
Air Separation and Liquefaction

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...
Need help comparing chest freezers and upright freezers
Currently we use in our Biobank an upright -80 freezer to store all our samples. We are planning to buy a fully automated bio-repository storage that will do the picking of samples under restricted conditions. But in the meantime I foresee that we have to pick the samples manually. The...
Need recommendations for cryogenic vials
I am looking into standardizing our range of bio storage tubes (cryogenic vials). These will be for both blood and tissue samples and their derivatives. Any recommendations, comments on Micronics, Nalgene, Nunc and or others that are suitable for long term -80 C and -196 C storage, DNA/RNA suitable, would...
We need a custom machine for flash freezing of water
We are an ice making company and have started a new project, which is related to flash freezing of water. It is based on cryogenics technology and we need a custom made machine. I would kindly ask you to pass me a few companies who would be interested in such...
Looking for a pump suitable for cold liquids
I would like to construct a small cooling circuit (appr. 50 x 50 cm) pumping liquid at a temperature down to -120°C from a cold reservoir to the specimen to be cooled. The tubes and connections are not a problem, but does somebody know a pump (suction/compression for circulation) suitable...
