Japan’s earthquake brings major science institutions to a standstill
In the wake of the March 11 earthquake that rocked Japan, major science experiments and research institutions are taking stock of the damage to their facilities and dealing with a number of setbacks.
Fermilab’s Alex Romanenko unlocks hidden secrets for improving SRF cavities
Fermilab’s Alex Romanenko recently unlocked secrets hidden beneath the mirror-smooth surface of niobium superconducting radiofrequency (SRF) cavities that may hold the key to the success of future linear colliders. Romanenko’s discovery, which was carried out as part of his doctoral thesis at Cornell University, has earned him “The Particle Accelerator...
UCLA Engineering establishes Endowed Chair in Cryogenics
UCLA Engineering has established the Traugott and Dorothea Frederking Endowed Chair in Cryogenics. The chair will support junior faculty for terms up to five years as they build their careers in areas related to cryogenics.
Lake Shore Cryotronics CEO appointed to PECSEA

Helium-3
Helium-3 (3He) is one of the two stable isotopes of helium. The other is the much more common Helium-4 (4He). Neither of these isotopes should be confused with He II, which is the second liquid phase of 4He. He II was discussed in this column in the Spring 2010 edition...
Cryopumping
Cryopumping refers to the use of cryogenic temperatures to produce vacuum in enclosed spaces. More broadly, it can also refer to the removal of gases via cryogenic temperatures from a flow stream or enclosure without necessarily resulting in vacuum pressures. This is an important application of cryogenics and is used...
Thermal Acoustic Oscillations
Thermal Acoustic Oscillations (TAO) are a common event in cryogenic systems that can have significant adverse effects on the performance of the system. TAOs are sustained pressure oscillations that can occur in tubes containing gas, closed at one end (the warm end) that have a very large temperature gradient along...
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...
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...
