Foundations of Cryocoolers Virtual Webinars

Plan now to join us for this in-depth exploration of all things cryocoolers! Normally presented in conjunction with the International Cryocooler Conference, the educational and experience-based Foundations of Cryocoolers Short Course is moving online with ICC. Perfect for cryogenic veterans and students alike, this online course will provide an invaluable...

ICCRT Postponed to 2021

Following restrictions imposed by Romanian Government to limit Covid19 outbreaks, including guidelines for organized indoor events, organizers of the International Conference on Cryocooler and Refrigeration Technologies were unfortunately constrained and made the decision to postpone the conference originally planned for October 7-10, 2020, in Bucharest to next year—the exact date...

Super-Kamiokande Gets an Upgrade to Detect Neutrinos from Ancient Supernovae

Buried 1-kilometer underground near the city of Hida, Japan, is a 40-meter tall cylinder filled with 50 million liters of water—the Super-Kamiokande neutrino observatory. Since 1996, it has been observing neutrinos—subatomic particles—from solar, extrasolar, terrestrial and artificial sources with highly sensitive optical sensors which record minute flashes of light that...

ASC to Hold All-virtual Conference October 24-November 7

The 2020 Applied Superconductivity Conference (ASC) will be held virtually over two weeks beginning October 24 and will offer a combined virtual platform for plenary, oral and poster presentations, a conference exhibition, a new program for young professionals called ELEVATE, virtual breakouts, coffee breaks and other features.

A Quantum Thermometer to Measure the Coldest Temperatures in the Universe

On August 20, Trinity College Dublin announced that physicists from the college have proposed a thermometer based on quantum entanglement that can accurately measure temperatures a billion times colder than those in outer space. These ultracold temperatures arise in clouds of atoms, known as Fermi gases, which are created by...

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...

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?

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).
