Goddard Goings: When NASA Went SHOOTING Into Orbit

The ’80s have been thrust back into our collective conscious! Hits such as Tracy Chapman’s “Fast Car” and “Running up that Hill” by Kate Bush have been introduced to a new generation by an incredibly popular cover of the first song and the repetitious use of the second in a...

Quantum Design Explores Quantum Frontiers with Precision Measurements

Since 1982, Quantum Design has been providing lab-ready scientific instruments to colleges, universities, government and corporate laboratories around the world. Instruments include the DynaCool® Physical Property Measurement System (PPMS), the MPMS3® SQUID Magnetometer and VersaLab® Physics Education System. The OptiCool® is a large volume, low vibration, low temperature and high...

Under Pressure: Harvard Scientists Break Through Precise Measurement with New Tool

Hydrogen (like many of us) acts weird under pressure. Theory predicts that when crushed by the weight of more than a million times Earth’s atmosphere, this light, abundant, normally gaseous element first becomes a metal and then, even more strangely, a superconductor – a material that conducts electricity with no...

The Next Generation in Cryogenics and Superconductivity

This feature introduces outstanding young professionals (under 40 years of age) who are doing interesting things in cryogenics and superconductivity and who show promise of making a difference in their fields. Debuted in the 2006 issue, the feature has presented many young persons whom we are proud to see have indeed lived...

Cryogenic Processors to Open Kentucky-Based Freeze-Dry and Packaging Site

Cryogenic freezing specialist Cryogenic Processors will open a new cryogenic freezing and freeze-drying facility in Paducah, Kentucky, at the end of 2024. The plant will feature three isolated pelletising rooms, each equipped with advanced blending systems and a standard conical pelletiser with an increased capacity of 1000kg per hour. Once pelletized,...

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...

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...

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...

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?
