Cold Testing Underway on ITER’s Toroidal Field Coils
Engineers from SIMIC S.p.a., a contractor based in Italy, have wrapped up the first round of cold testing the toroidal field coils manufactured for ITER, a process that involved submitting the coil winding pack to a thermal cycle between room temperature and 80 K.
New Superconducting Cable Surfaces from Research Supporting US Navy
A research team from Florida State University’s Center for Advanced Power Systems and the Colorado-based Advanced Conductor Technologies LLC has demonstrated the first high-temperature superconducting direct current power transmission cable using ACT’s Conductor on Round Core (CORC) cable technology. The cables enable transmission of vast amounts of power at high...
Stirling Power Generator Recovers Both Cold Energy and Waste Heat
Plans for recovering LNG cold energy have become an important focus in the LNG industry and show great potential for increasing energy efficiency and reducing carbon emission.
Companies Adapt Cryocooler Technology for New Applications
Cryocoolers are making inroads into commercial applications and are getting closer to our everyday lives. It is well known in the cryogenics community that cryocoolers have been in increasing demand for wider applications.
Researchers Hunting Exoplanets with Superconducting Arrays
The key to revealing the exoplanets tucked away around the universe may just be locked up in the advancement of Microwave Kinetic Inductance Detectors (MKIDs), an array of superconducting detectors made from platinum sillicide and housed in a cryostat at 100 mK.

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...
Wind Tunnels
Dr. Robert Kilgore The development of the cryogenic wind tunnel is one of many significant breakthroughs in both cryogenics and wind-tunnel technology made during the past millennium. Interest in the development of high-speed commercial and military aircraft resulted in a review of problems of flow simulation in transonic wind tunnels...
History of Cryogenics
From the Fall 1999 issue of Cold Facts magazine Millennium Breakthroughs A variety of CSA members give different perspectives on the past millennium: What were the most significant breakthroughs in cryogenics during the past millennium? Prof. R.G. Scurlock, Kryos Technology, scurlock@soton.ac.uk (“Breakthrough” = way through obstacles — Oxford English Dictionary)...
Cryobiology
Andreas Sputtek Past President Society for Cryobiology sputtek@uke.uni-hamburg.de or http://www.sputtek.de/. The word cryobiology (from the Greek words “cryo” = cold, “bios” = life, and “logos” = science) literally signifies the science of life at low temperatures. In practice, this field comprises the study of any biological material or system (e.g.,...
Cryogenic Insulation
James E. Fesmire Cryogenics Test Laboratory NASA Kennedy Space Center james.e.fesmire@nasa.gov Introduction In today’s world, the use of cryogenics and low-temperature refrigeration is taking a more and more significant role. From the food industry, transportation, energy, and medical applications to the Space Shuttle, cryogenic liquids must be stored, handled, and...
Cryogenic processing for medical equipment, mining industry
Greetings from Australia. I am looking for a company that I might contact that has any experience or has done any research into cryogenic processing for medical equipment, in particular, joint prosthesis.
Cryogenic sealant for LNG fueled buses?
Where can I find a cryogenic sealant for my LNG fueled buses?
Material/gel/epoxy to transfer cold temperature of a cryo-box to a test article
I’m on the hunt for a material/gel/epoxy that will transfer the cold temperature of a cryo-box to a test article. The cryo-box is curved and the test article is at the same curvature. I’m looking for something to put between them to make the surface of the test article as...
