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...

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 Electronics

Randall Kirschman, consulting physicist, Mountain View, California ExtElect@gmail.com Cryogenic electronics—the operation of electronic devices, circuits, and systems at cryogenic temperatures—has been a valuable technology for decades. Cryogenic electronics (also referred to as low-temperature electronics, or cold electronics) can be based on semiconductive devices, on superconductive devices, or on a combination...

Particle Physics: High Energy Physics

Cryogenics and High-Energy Physics 1. From symmetry magazine: http://www.symmetrymagazine.org/cms/?pid=1000627: Cryogenics is the study of how materials behave at temperatures near absolute zero. In high-energy particle accelerators, such frigid temperatures reduce the electrical resistance of wires in superconducting magnets, increasing the magnet strength and allowing faster particle acceleration. The same holds...

HTS Degaussing Systems

From the Spring 2009 issue of Cold Facts (Volume 25, Number 2): Thanks to a joint project by the US Navy and a number of industry partners, high temperature superconducting (HTS) technology is now at the heart of an advanced degaussing system aboard the USS Higgins at the naval station...

Magnetic Resonance Imaging

From http://www.superconductors.org: An area where superconductors can perform a life-saving function is in the field of biomagnetism. Doctors need a non-invasive means of determining what’s going on inside the human body. By impinging a strong superconductor-derived magnetic field into the body, hydrogen atoms that exist in the body’s water and...

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...
