Dippin’ Dots reacts to the marketplace
Would you like your coffee regular, black or pelletized? The question is important to the makers of Dippin’ Dots, those supercold beads of ice cream that are sold largely at ballparks and amusement parks and have become a staple of childhood summers.
CERN/ITER collaboration rescues Japanese magnet project
The iter newsline reports that when the March 2011 earthquake that devastated Japan dramatically disrupted a quality control step in the manufacturing process of the superconducting wires for the ITER magnets, swift action by CERN allowed the verification process to proceed.
US ITER SC magnet contract goes to General Atomics
The US ITER Project Office at Oak Ridge National Laboratory competitively awarded a multi-year contract to General Atomics to produce superconducting magnets for the central solenoid of ITER, an experimental fusion facility that aims to demonstrate the feasibility of fusion energy for the commercial power grid.
US Helium Reserve nearing depletion
Officials at the Federal Helium Reserve, the source of almost half of the US helium supply and more than a third of the world's, say that the reserve could exhaust its supply by 2020.
Hints of Higgs boson detected at Tevatron, LHC
Scientists of the CDF and DZero collaborations at Fermilab continue to increase the sensitivity of their Tevatron experiments to the Higgs particle and narrow the range in which the particle seems to be hiding.

Transfer Lines
Transfer lines may in some real sense be thought of as the cryogenic fluid analogy of current leads. While current leads carry electrical power to where it’s required in a cryogenic system, transfer lines do the same with cryogenic fluids. Transfer lines range in complexity from very simple U-tubes containing...
Zero Boiloff
Zero Boil Off cryostats are those that contain liquid cryogens but are designed to eliminate or vastly reduce the boil off of the liquid. These cryostats combine some of the advantages of Cryogen-Free systems (e.g. ease of use and long operational lifetime) with the advantages associated with a reservoir of liquid...
Cryomodule
Cryomodule is a term that is most commonly used to refer to cryostats that contain superconducting radio frequency (SRF) cavities. Such cavities are used to accelerate charged particle beams and are a major component of modern particle accelerators. Using the term cryomodule to refer to cryostats containing SRF cavities appears...
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...
Company to design and manufacture a portable gas purity monitoring system
I am looking for a company to design and manufacture a portable gas purity monitoring system using a cryostat/dewar/flow meter combination.
Consultant knowledgeable in LNG
My company is seeking a consultant who is knowledgeable in LNG. It is a project located overseas, and involves a refinery and heat exchangers. Can anyone provide me with a reference?
LN2 flow in cryotherapy device
I’m working on a cooler device that will be pretty similar to the devices commonly used in cryotherapy for cooling skin.
Source for small gas liquefier/cryocooler?
I would like to acquire a used gas liquefier/cryocooler for use in my non-profit project to build a high-performance natural gas (methane) powered car. I am interested in liquefying piped natural gas (methane) into LNG (about 120K or -154 degrees).
