Cryogenics in Motion: Spaceline Delivers Advanced Nitrogen Trailer for NASA Armstrong

Spaceline Technologies, a fluid system engineering and manufacturing company, has completed a cryogenic nitrogen transport and supply trailer for NASA Armstrong Flight Research Center. This trailer is a mobile and standalone solution to provide pressure regulated nitrogen gas and liquid with flowrate and temperature control. Control of the trailer can...

Cryogenics and the Road to Superconducting Propulsion: Part I for Aircrafts

by Quan-Sheng Shu, cryospc.com and Jonathan Demko, Le Tourneau University Superconducting (SC) motors are pivotal for future transportation, offering power densities exceeding 20 kW/kg. Cooling philosophies diverge by architecture: partially superconducting aircraft designs (like NASA’s HEMM) utilize integrated mechanical cryocoolers for the rotor, whereas fully superconducting aircraft favor liquid hydrogen...

Pelican Wire Designs for Cryogenic and Extreme Energy Systems

As renewable energy, electrification and advanced research technologies continue to expand, the demands placed on wire and cable systems are evolving just as rapidly. Higher power densities, tighter system integration and increasingly extreme operating environments are pushing manufacturers beyond traditional commodity wire solutions. Caleb Lemmons, Business Development Manager at Pelican...

Meet the 2026 Young Professionals

This feature introduces outstanding young professionals (under 40 years of age) who are doing interesting things in cryogenics and superconductivity and who show promise of making a difference in their fields. Debuted in the 2006 issue, the feature has presented many young persons whom we are proud to see have...

Extraterrestrial Specifications for Cryogenic Fluid Production

by Wesley Johnson, NASA Glenn Research Center Here on our home planet, where we have been liquefying various “permanent gasses” since 1877 [1], most of us take it for granted that when we go out to buy a cryogenic liquid (or even a pure gas) we don’t have to write...

Cold Power: How Cryogenics Will Make Chicago the Taiwan of Quantum Computing

by Joe Procunier, LJC Design & Engineering Chicago is set to redefine the future of quantum computing, just as Taiwan reshaped the global semiconductor industry. In 1987, Morris Chang famously started TSMC (Taiwan Semiconductor Manufacturing Company) after working as a pivotal figure at Texas Instruments.[1] The Taiwanese government encouraged him...

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

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...
