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...

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...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...
