An Introduction to LNG as a Cryofuel

Technological advances in the US have unlocked massive quantities of natural gas, resulting in an abundant supply that should easily last many decades. This sustained situation has created two important consequences: the price of pipeline natural gas is low and stable, and, more significantly, the price of pipeline natural gas...

Improving the Efficiency of Helium Transfer Tubes

One must, on a daily basis, transfer liquefied gases, most notably helium from large static tanks or dewars to smaller transportable vessels. This process can become costly due to the losses sustained during transfer, which must be compensated for by reliquefying helium, requiring between 2 and 5 kW per liquid...

MiniCLEAN detector begins search for dark matter

Researchers at Pacific Northwest National Laboratory, after eight years of designing and building, have begun commissioning and cooling the MiniCLEAN detector, a small experiment with the big goal of detecting dark matter. CLEAN stands for Cryogenic Low-Energy Astrophysics with Nobles. Scientists will use the detector to search for weakly interacting...

CSA protests misleading NY Times front page cryonics story

CSA Executive Director Laurie Huget responds to a September 13 front page New York Times article by Amy Harmon on Kim Suozzi, a young woman who decided to have her brain put on storage by cryonics.

Air Liquide expands its business in Turkey

Air Liquide advanced Technologies expanded its foothold in Turkey on September 15 with the acquisition of Messer Aligaz Sanayi Gazlari, a subsidiary of industrial gas company Messer Group GmbH. Messer Aligaz provides industrial, medical and specialty gases to a range of industries in Turkey. The company owns and operates an...

Researchers observe dynamic Mott transition in superconductors

An international team of researchers, including the MESA+ Institute for Nanotechnology at the University of Twente in The Netherlands and the US Department of Energy’s Argonne National Laboratory (CSA CSM), has announced the first observation of a dynamic Mott transition in a superconductor. The discovery experimentally connects the worlds of...

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

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...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
