Ready to launch the prototype: HTS current leads for ITER
High Temperature Superconductor (HTS) current leads are the components that transmit the large currents from room-temperature power supplies to very low-temperature superconducting coils.

High-tech storage holds the key to preserving plant life
About half the world's plant species are estimated to be under threat of extinction, and Australia is home to 14 percent of them. It is now hoped a cryogenic storage unit can protect Australia's native plants forever.
Bestobell supplies valves for first US LNG flag vessel
The first US flag vessel to be operated on liquefied natural gas uses valves supplied by Bestobell Valves (CSA CSM). Globe and check valves were supplied as part of the LNGPac fuel system through the company’s preferred supplier agreement with Wärtsilä Gas Power Systems (GPS).
Scientists create first computer-designed superconductor
A Binghamton University scientist and his international colleagues report on the successful synthesis of the first superconductor designed entirely on the computer. Their findings were published in Physical Review Letters.
Higgs, Englert Win Nobel for Particle Mass Discoveries
On October 8 François Englert of Belgium and Peter Higgs of Britain were awarded the 2013 Nobel Prize in physics for their theoretical discoveries on how subatomic particles acquire mass.
VIDEO: A guided tour around the CLIC test facility
The Compact Linear Collider (CLIC) is a study for a future accelerator that will reach unprecedented energies for electrons and their antimatter twins, positrons.

Two-Phase Flows
Two-phase flows are those flows in which there is a mixture of two physical states (solid, liquid or vapor). In cryogenic applications, such flows are almost always a mixture of a cryogenic liquid along with its corresponding vapor. A mixture of liquid helium and helium vapor would be a typical...
Supercritical Fluids
A supercritical fluid is defined as a substance whose temperature and pressure exceed those of its critical point. Every pure substance has a critical point that is defined in thermodynamic space by a critical temperature and a corresponding critical pressure. For example, the critical point for helium has a critical...
Brayton Cycle
The Brayton cycle is one of the many thermodynamic cycles used to generate cooling at cryogenic temperatures. Strictly speaking, when referring to cooling we should call this the reverse Brayton cycle as the original Brayton cycle describes the process of power generation or propulsion via a gas turbine. In many...
Air Separation and Liquefaction
by Nils Tellier, PE, President, EPSIM Corporation (CSA CSM) nils@epsim.us All illustrations courtesy EPSIM Corporation Background History of Air Separation and Liquefaction This section builds on a rich history of methods to develop deep refrigeration and cryogenic liquefaction during the 19th Century. 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...
Reliability and mounting of electronic substrates at low temperatures
I am currently working on the design of a focal plane assembly to be implemented on a small satellite (4 EMCCD detectors) to be operated at -80°C (which is not really cryogenic and likely still considered boiling hot for most of you :-). As it is passively cooled, the assembly...
Are 3D drawings included in the sale of a cryogenic plant?
I have a question concerning the 3D drawings of a cryogenic plant. The integration of the 3D drawings of a plant with the 3D main model of a new laboratory or a new facility can be a complex work that takes a lot of time. I would like to know...
Looking for a source of LOX impact testing to ASTM D2512
I have been looking for a source of LOX impact testing to ASTM D2512. I am aware of NASA and White Sands, but am looking for a commercial entity doing the work. No luck so far, even calling a lot of the folks on the CSA website. Any referrals will...
