New Study Could Help Pinpoint Hidden Helium Gas Fields

Research led by the University of Oxford could help overturn the current supply crisis of helium, a vital societal resource. The study proposes a new model to account for the existence of previously unexplained helium-rich reservoirs. The findings, published in Nature, could help locate untapped reservoirs of accessible helium. Dr. Anran...

H2FLY Announces Liquid Hydrogen Filling Success

German-based H2FLY has announced success from a liquid hydrogen filling test of its HY4 hydrogen-electric aircraft. The on-ground test at Air Liquide’s Campus Technologies Grenoble in France saw liquid hydrogen fill the aircraft’s new liquid hydrogen storage system, designed and supplied by Air Liquide. Coming as a precursor to future tests in...

Delft Circuits Chosen by NASA JPL Scientist to Support BICEP Project in Antarctica

Delft Circuits announced its inclusion in the Background Imaging of Cosmic Extragalactic Polarization (BICEP) project in Antarctica, supporting NASA’s Jet Propulsion Laboratory at CalTech and other project partners. BICEP has been ongoing for several years and is now seeking solutions for a hardware upgrade to its telescope’s sensitivity as the...

Vulcan: Tanking tests performed on ULA’s new rocket

Completing the next phase of testing in preparation for the inaugural Vulcan rocket flight, the United Launch Alliance (ULA) team accomplished tanking demonstrations at Cape Canaveral Space Force Station, Florida. The pathfinder tests filled the Vulcan first stage and Centaur V upper stage with cryogenic propellant on separate days to validate...

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...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...

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...
