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...

JanisULT, Formerly Janis Research, Launches New Website

In August 2020, Janis Research Company, LLC (CSA CSM) announced a formal change in company name to JanisULT (a trading name of American ULT Cryogenics, LLC) following the successful sale of their laboratory cryogenics business to Lake Shore Cryotronics (CSA CSM). On March 12, the company announced their updated website,...

IceCube Detection of a High Energy Particle Proves 60-Year-Old Theory

On December 6, 2016, a high energy particle called an electron antineutrino hurtled to Earth from outer space at close to the speed of light carrying 6.3 petaelectronvolts of energy. Deep inside the ice sheet at the South Pole, it smashed into an electron and produced a particle that quickly...

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

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?
