Cold Facts Digital – The go-to place for Cryogenics and Superconductivity

Introducing Cool Fuel: Fueling Cryogenics for the 21st Century!

There’s no shortage of cool project areas in cryogenics these days: space, quantum computing, fusion energy, clean energy and clean transport, to name a few. These are the fields that aspiring new engineers want to work in when they pass through my office. The irony is that our cool field...

Cryogenic Industrial Gas to Play Major Role in Alternative Clean Energy

While industrial gases and cryogenics have touched nearly every sector and industrial market for decades, the global push towards alternative clean energy technology is pushing cryogenics more rapidly than ever before. As part of this push, Circor (CSA CSM) is setting new standards for a hydrogen energy world. New technologies...

It’s Chilly Here: Lowest Temperature at Fermilab Reached in Equipment for Dark Matter Experiment

When Fermilab (CSA CSM) scientists Matt Hollister and Dan Bauer make the journey this summer to install the new SuperCDMS dilution refrigerator at SNOLAB near Sudbury, Ontario, Canada, this development will have been made possible by a milestone reached in late October. Fermilab SuperCDMS scientists cooled their dilution refrigerator down...

Saving Breaths: The Literal Air Power

When any of Cannon Air Force Base’s aircraft leave the base located just outside Clovis NM, members of the 27th Special Operations Logistics Readiness Squadron (SOLRS) cryogenics team make sure that, should anything go wrong, the pilots and crew can breathe easy… literally. The cryogenics team provides the liquid oxygen...

Quantum Fluctuations Sustain Record Superconductor

Calculations performed by an international team of Materials Physics Center researchers representing Spain, Italy, France, Germany and Japan show that the crystal structure of the record superconducting LaH10 compound is stabilized by atomic quantum fluctuations. This result suggests that superconductivity approaching room temperature may be possible in hydrogen-rich compounds at...

Indian Railways to Inaugurate Hydrogen Powered Train

India Railways is developing a hydrogen powered suburban train and has floated an official expression of interest for industry participation. The move is part of the railway’s efforts at greening its fuel use. Indian Railways has already fitted solar panels on rooftops of diesel electric multiple unit trains of 4.5...

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...
