Jefferson Lab Sets Date for 2022 Open House Event

The Department of Energy’s Thomas Jefferson National Accelerator Facility (Jefferson Lab, CSA CSM) will open its doors to the public for its next Open House event on March 26, 2022. The free event will offer an opportunity for people of all ages to explore Jefferson Lab’s world-class research facility, including...

A Breakthrough For Electric and Hydrogen-powered Aircraft

A major breakthrough in electric propulsion for long-range aircraft could soon be on the horizon. The presence of a cold source, in the form of liquid hydrogen, alongside superconducting technologies promises to unlock new possibilities. The ASCEND demonstrator project by Airbus UpNext aims to mature these technologies to significantly boost...

NASA SLS Green Run Testing Complete, Boeing Readies Core Stage for Tow to Florida

NASA’s Space Launch System (SLS) program and prime Core Stage contractor Boeing wrapped up the Green Run testing campaign on the Artemis 1 flight article at the Stennis Space Center and are readying the vehicle for its long-awaited shipment to the Kennedy Space Center in Florida. After reviewing the performance...

SpaceX Conducts Cryogenic Test on Starship SN15

On April 13, Starship SN15 went through the cryogenic proof test. The cryo-test ensures if a spaceship is able to withstand in-flight atmospheric pressures and extremely low temperatures. This is achieved by simulating the in-flight conditions by filling the Starship with liquid nitrogen that has a temperature of −196 °C...

Researchers Develop Cryogenic Coffee Grinding Technology

Skoltech Ph.D. Dima Smirnov and his colleagues from St. Petersburg, Alexander Saichenko, Vladimir Dvortsov, Mikhail Tkachenko and Maxim Kukolev developed a cryogenic cooling technology and combined it with a cryogenic grinding technique to produce, for the first time ever, retail cryoground coffee.

Honoring the Hugets

After 42 years of continued leadership and direction, Laurie and Werner Huget have retired from CSA. For decades, the Hugets have overseen CSA’s day-to-day operations, organized conferences and workshops attended by professionals from around the world and facilitated countless short courses for the cryogenics community. We invite you to continue...

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...

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 Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...
