Altus Midstream Announces First Cryogenic Processing Train in Service at Texas Complex
Altus Midstream introduced the first of its three new cryogenic processing trains at the Diamond Cryo Complex in Alpine High TX. It is now processing rich natural gas and delivering natural gas liquids (NGLs) and residue gas for sale.
Department of Energy Announces $75 Million for High-Energy Physics Research
The US Department of Energy recently announced grants of $75 million in funding for 66 university research awards. The projects involve scientists at 51 US institutions of higher learning and include both experimental and theoretical research into topics like the Higgs boson, neutrinos, dark matter, dark energy and the search...
Blue Origin Test-Fires Moon Lander Engines
Blue Origin recently fired up a brand-new engine, the BE-7, which the company developed for its future moon lander. Founder and CEO Jeff Bezos claims the lander, equipped with the BE-7, will be capable of carrying robotic rovers to the moon or even a separate spacecraft that can take off...
Air Liquide Signs Two Long-Term Oxygen Supply Agreements with Marathon Petroleum Corporation
Air Liquide advanced Technologies (CSA CSM) has signed two long-term supply agreements with Marathon Petroleum Company for a total of up to 900 tons of oxygen per day for Marathon Petroleum’s Refineries on the American Gulf Coast.
Shaw Prize in Astronomy Awarded to Edward Stone
Former Jet Propulsion Laboratory director Edward Stone has been awarded the prestigious Shaw Prize in Astronomy for his leadership in the Voyager project. The Shaw Prize is awarded annually in three categories: Astronomy, Life Science and Medicine, and Mathematical Sciences, and comes with a monetary prize of $1.2 million. Stone...

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...
Any experience with Tungsten or Tantalum metal springs in a low temp environment?
I would like to use metal springs made of Tungsten or Tantalum in low temperature environment. Does anybody have any experience with such springs? More precisely, I would like to make compression springs by rolling tungsten or tantalum wire on a rod. I expect that, typically, the spring constant will...
Standards & specifications for pipe & tube couplings
I am interested in finding out more about cryogenic applications and what standards, specifications and test methods (ASTM, etc.) are required for qualification of pipe and tube couplings.
Looking for a test house to test the static coefficient of friction under cryogenic conditions
I am looking to find a test house that is capable of testing the static coefficient of friction under cryogenic conditions. We can be flexible on most of the test parameters, including the test coupon configuration, but we’re looking for a test house that can provide the following test environment:...
Approximating pressure changes over time in cryogenic cylinders
I am an Air Resources Engineer with the California Air Resources Board (CARB). My senior management has asked me to investigate approximating pressure changes over time in cryogenic cylinders that contain LNG. So far, I have taken a stab at the problem, seeking to take a back-of-the-envelope approach (as directed...
