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...

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...

FDA accepts BioCision’s ThawSTAR master file

The US Food and Drug Administration (FDA) this month accepted the Device Master File (MAF) submission for BioCision's ThawSTAR automated cell thawing system. The ThawSTAR MAF encompasses information pertaining to the specifications, materials and quality and manufacturing processes used in producing the ThawSTAR system.

Study shows economics impact of cryogenics in UK

A study by Warwick Economics & Development (WECD) that was commissioned by the Science & Technology Facilities Council shows that the UK's strong cryogenics community delivers substantial economic impact to the country's economy. Based on supply chain analysis, WECD estimates that sectors broadly associated with cryogenics represent 17 percent of...

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...
