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...

Liquid Hydrogen

Hydrogen becomes a liquid at 20K and 1 bar. Liquid hydrogen (LH2) is an important substance in industry, transportation and research. Industrial uses of hydrogen include applications in the electronics, glass, chemical and metal processing fields. In these applications, the hydrogen is generally used as a room temperature gas but...

Superconducting Radiofrequency Cavities

Superconducting radio frequency (SRF) cavities represent an important application of cryogenics and superconductivity. SRF cavities are a technology for accelerating charged particle beams via the transfer of radiofrequency (RF) energy to the beams via resonant structures. As such, they are frequently found in large particle accelerators used for scientific research....

Thermal Radiation Shields

Actively cooled thermal radiation shields are a common feature of cryostats whose lowest temperature is less than 77K. These shields, which typically operate at temperatures between that of LN2 and 40K, block thermal radiation from higher temperatures from reaching lower temperature cryogenic components or fluids. Since the heat radiated from...

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...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
