CryoHiVac Investigates Cryogenic Market, Affordability from Earth to Space

Today’s time-sensitive market needs revolutionization of traditional costly technologies. The cryogenic and electronic market development and utilization started from 1970 for commercial applications, and both are fast-growing technologies. There has been significant advancement of electronic products. Nowadays, a small smartphone has much more data storage and processing power capability than...

Dark Energy Spectroscopic Instrument (DESI) Creates Largest 3D Map of the Cosmos

The Dark Energy Spectroscopic Instrument (DESI) has capped off the first seven months of its survey run by smashing through all previous records for three-dimensional galaxy surveys, creating the largest and most detailed map of the universe ever. Yet it’s only about 10% of the way through its five-year mission....

Demaco Produces ESS Hydrogen Distribution System

Hydrogen is the most abundant chemical element in the universe and the most important feedstock for life. In Greek, the word “hydrogen” is composed of the terms “hydro” and “genes,” which means water generator. In 1766, the English chemist Henry Cavendish distinguished hydrogen from other flammable gases and identified its properties,...

Ability Engineering Technology Introduces Ultra Precise Cryo Valve to Public

Ability Engineering Technology (AET), an Illinois-based manufacturer of equipment used in cryogenic process applications, has announced the introduction of a standard product line of Cryogenic Valves. According to Matt Resler, Sales Director at AET, “Our cryogenic valves have been successfully used for more than 30 years by our DOE clients, and...

Space Cryogenic Workshop Recap

During a year filled with uncertainty, many were worried about the effects of the pandemic on CSA’s biennial Space Cryogenics Workshop (SCW). After much consideration and effort, we are pleased to report the successful execution of our first – and hopefully only – virtual SCW. Hosted virtually on the Remo®...

Fermilab Sees Record Performance from Next-Generation Accelerator Componen

For several years, three US Department of Energy national labs have worked together to further improve state-of-the-art particle accelerator technology. First tests of a prototype built at Fermi National Accelerator Laboratory (Fermilab, CSA CSM) show the effort has paid off, with a new component setting records. The technology under development...

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...
