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...

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...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...
