28th Space Cryogenics Workshop

CSA and NASA’s Cryogenics Technical Discipline Team announce the 28th Space Cryogenics Workshop, to be held July 17-19, 2019, at the Heritage Hotel, Southbury CT. All aspects of space cryogenics will be represented, with an emphasis on those related to space exploration.

ISRU Research Holds Promise for Space Exploration

First explored for cryogenic use in space exploration, ISRU has expanded further and today involves hardware and operations that harness and utilize local in-situ resources to create products and services for robotic and human exploration.

Start Your Cryogenics Career with a Boom!

Dr. Jacob Leachman never got to meet Dr. Boom, but says he got to know him through a legacy of accomplishments, including Boom's passion for inspiring students to enter the field.

Physicists Uncover State of Matter in Superconducting Material

A team from Ames Laboratory and the University of Alabama Birmingham has discovered a remarkable new state of matter within an iron pnictide superconductor, revealing a laser-induced formation of collective behaviors that compete with superconductivity around 16 K.

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...

Sealant Adhesive KAE 89?

Can you give me contact details for the manufacturer of a “sealant Adhesive” KAE 89? It is a vapor stop, used on insulation covering LNG carrying conduits. This is a suggested alternative to Foster 90-66. Do you have details of any other alternative products for this application?
