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...

Scientists Create Compact Particle Accelerators, Enable Strobe Photography of Atomic Motion

Early in August, scientists at the University of Machester successfully developed a pocket-sized particle accelerator capable of projecting ultrashort electron beams with laser light at more than 99.99% of the speed of light. To achieve this result, the researchers had to slow light to match electron speeds using a specially...

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...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...
