Bestobell supplies valves for first US LNG flag vessel

The first US flag vessel to be operated on liquefied natural gas uses valves supplied by Bestobell Valves (CSA CSM). Globe and check valves were supplied as part of the LNGPac fuel system through the company’s preferred supplier agreement with Wärtsilä Gas Power Systems (GPS).

Scientists create first computer-designed superconductor

A Binghamton University scientist and his international colleagues report on the successful synthesis of the first superconductor designed entirely on the computer. Their findings were published in Physical Review Letters.

Higgs, Englert Win Nobel for Particle Mass Discoveries

On October 8 François Englert of Belgium and Peter Higgs of Britain were awarded the 2013 Nobel Prize in physics for their theoretical discoveries on how subatomic particles acquire mass.

VIDEO: A guided tour around the CLIC test facility

The Compact Linear Collider (CLIC) is a study for a future accelerator that will reach unprecedented energies for electrons and their antimatter twins, positrons.

UCSB researchers make headway in quantum information transfer

Fiber optics has made communication faster than ever, but the next step involves a quantum leap—literally. In order to improve the security of the transfer of information, scientists are working on how to translate electrical quantum states to optical quantum states in a way that would enable ultrafast, quantum-encrypted communications.

GE expands small-scale LNG business

In connection with its recent acquisition of substantially all the assets of the Salof Companies, GE Oil & Gas announced that it has completed its acquisition of a 50 percent ownership interest in Beijing enCryo Engineering Co., Ltd., a Beijing-based joint venture with Beijing Maison Engineering Co., Ltd. that specializes...

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...

Magnets

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. Particle physics uses accelerators to recreate the conditions of the early universe in an attempt to piece together the complex puzzle of how we got to where we are today. These huge machines are used...

Energy Storage

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. With power lines increasingly congested and prone to instability, strategic injection of brief bursts of real power can play a crucial role in maintaining grid reliability. Small-scale Superconducting Magnetic Energy Storage (SMES) systems, based on...

Astronomy

ASTRONOMY IN SPACE by Peter V. Mason, retired, Jet Propulsion Laboratory, and Visiting Associate, California Institute of Technology. Pmason@alumni.caltech.edu In thinking about the reasons to perform astronomy in space, we first consider the effect of the earth’s atmosphere. On a scale of decreasing energy, gamma rays, cosmic rays, X-rays and...

Cryocoolers

What is a Cryocooler? A mechanism that can extract heat from an object (cooler) and by doing so draw its temperature down below approximately 150 Kelvin (cryo). — (Courtesy Dr. Willy Gully) What is the difference between a Cryocooler and a Cryostat? A cryostat is any device designed to maintain...

Containing ice accumulation while recovering helium

We are implementing a system to recover helium from our Janis ST-500 continuous flow LHe cryostat. The recovery system uses standard 1/4″ plastic tubing, which we connect directly to the cryostat’s exhaust port. The problem with this setup is that the gas is still quite cold as it leaves the...

Looking for some advice regarding cryogenic modeling in ANSYS FEA software

I am looking for some advice regarding cryogenic modeling in ANSYS FEA software. I have been trying to use the Transient Thermal module, in workbench 14.5, to model the cooling of a device in a dilution fridge. I have approximate values for the cooling power of each plate in the...
