Space Cryo Workshop 2025 Sparks Collaboration Across Continents

By Wesley Johnson and Dan Hauser The 31st Space Cryogenics Workshop (SCW) was held at the Hyatt Regency Lake Tahoe in Incline Village, Nevada, from May 13 to 15, 2025, chaired by Wesley Johnson and Daniel Hauser. More than 60 scientists and engineers from around the world convened to discuss...

Tiny Cryogenic Device Cuts Quantum Computer Heat Emissions By 10,000 Times

Researchers have developed a tiny device that extinguishes one of the biggest heat sources in quantum computers, cutting their running costs and potentially bringing these machines closer to commercial reality. Most quantum computers operate at temperatures close to absolute zero (459.67 degrees Fahrenheit, or minus 273.15 degrees Celsius) using specialized cooling equipment to...

U of W Teams Sets Record for ‘Cool’ Science’

Over the summer, Dr. Jeff Martin, chair of the physics department at the University of Winnipeg (U of W), tripled his past record for ultracold neutron production at TRIUMF, Canada’s particle accelerator centre. With the help of Dr. Russell Mammei, Dr. Blair Jamieson and several graduate and undergraduate students, Martin...

Nikkiso Contracted for Bahamas LNG-to-Power Project

Nikkiso Clean Energy & Industrial Gases Group has been contracted by NPG (a joint venture to be formed by Shell and a subsidiary of FOCOL Holdings Limited) to provide liquefied natural gas (LNG) regasification and cryogenic equipment for the New Providence Gas Project in Nassau, the Bahamas. The project involves...
Researchers Build Einstein Telescope Pathfinder with 10 km Arms and 10–15 K Cryogenic Mirrors

Researchers Build Einstein Telescope Pathfinder with 10 km Arms and 10–15 K Cryogenic Mirrors

The search for gravitational waves continues to push the boundaries of precision measurement, and the next generation of detectors promises to reveal previously inaccessible cosmic events. Thomas Höhn, Adrian Schwenck, and Thomas Thümmler, from the Karlsruhe Institute of Technology, alongside the Einstein Telescope Pathfinder (ET-PF) collaboration, are developing crucial technologies...

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...
