New Partnership with Druck set for Major Breakthrough in Hydrogen-Powered Aircraft

The University of Bath has entered a Knowledge Transfer Partnership (KTP) with Druck, a Crane Company business, to develop the world’s first flight-certified cryogenic hydrogen pressure sensor, helping pave the way for net-zero aviation. Hydrogen is one of the most promising solutions to decarbonising air travel, with aviation currently accounting...

In Memoriam: Dr. Ray Radebaugh

It is with deep sadness that we share the passing of Ray Radebaugh. Ray was a pioneer, mentor, and friend whose influence on cryogenics spanned more than five decades and touched nearly every corner of our field. Ray’s passion for engineering began early. Growing up in Mishawaka, Indiana, he learned...

New Cryogenic Vacuum Chamber Cuts Noise for Quantum Ion Trapping

by John Toon, Georgia Institute of Technology Even very slight environmental noise, such as microscopic vibrations or magnetic field fluctuations a hundred times smaller than Earth’s magnetic field, can be catastrophic for quantum computing experiments with trapped ions. To address that challenge, researchers at the Georgia Tech Research Institute (GTRI)...

Remembering Bruce P. Strauss, a Steward of the Superconductivity Community

The superconductivity community has lost one of its most devoted stewards with the passing of Bruce P. Strauss, whose career spanned more than five decades and whose influence reached far beyond his own technical work. Bruce was not only a contributor to applied superconductivity; he was a builder of the...

Transfer Lines

Transfer lines may in some real sense be thought of as the cryogenic fluid analogy of current leads. While current leads carry electrical power to where it’s required in a cryogenic system, transfer lines do the same with cryogenic fluids. Transfer lines range in complexity from very simple U-tubes containing...

Zero Boiloff

Zero Boil Off cryostats are those that contain liquid cryogens but are designed to eliminate or vastly reduce the boil off of  the liquid. These cryostats combine some of the advantages of Cryogen-Free systems (e.g. ease of use and long operational lifetime) with the advantages associated with a reservoir of liquid...

Cryomodule

Cryomodule is a term that is most commonly used to refer to cryostats that contain superconducting radio frequency (SRF) cavities. Such cavities are used to accelerate charged particle beams and are a major component of modern particle accelerators. Using the term cryomodule to refer to cryostats containing SRF cavities appears...

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...
