NASA’s Webb Identifies Methane In an Exoplanet’s Atmosphere

NASA’s James Webb Space Telescope observed the exoplanet WASP-80 b as it passed in front of and behind its host star, revealing spectra indicative of an atmosphere containing methane gas and water vapor. While water vapor has been detected in over a dozen planets to date, until recently methane – a molecule...

Cryogenics Impacts Life Sciences

“It’s too hot, it’s too cold.” We have all heard those famous words from family, friends, coworkers or feedback from instrumentation. Whether it is to control temperature in a confined environment, rotating equipment, or bioprocessing, cryogens are utilized throughout industries. At times, valves are overlooked as an integral part of...

Ovarian Tissue Cryopreservation Offers Hope in Canada

A monumental program centered on ovarian tissue cryopreservation is offering hope to women and girls across Canada. Dr. James Benson, a world-renowned cryobiology expert, leads this transformative initiative. This medical procedure safeguards healthy ovarian tissue before cancer treatments can harm it, ultimately enabling female patients to have biological children in...

Why Are Quantum Technologies So Cool?

Efforts to build a useful quantum computer are underway, with startup companies competing alongside the big leaders in information technology. Other quantum technologies are already part of our everyday lives, from MRI scanners in hospitals to atomic clocks, which are used to keep precise track of time on GPS satellites...

Unleashing Hydrogen—a Paradigm Shift in Energy Storage and a Sustainable Future

As the wheels of innovation propel society forward, some elements of our technological landscape remain entrenched in the past, seemingly impervious to the tides of change. The heating oil tank, a relic from a different era, stands as a testament to this phenomenon. In a time when the urgency of...

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...

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?
