New Light Source construction more than 70 percent complete

Construction of the $912-million National Synchrotron Light Source II (NSLS-II) at the U.S. Department of Energy’s Brookhaven National Laboratory is more than 70 percent complete – on schedule and on budget.

Ames Lab’s Canfield makes mark in condensed matter physics

Paul Canfield, a physicist at DOE’s Ames Laboratory, is known for his skill in synthesizing and characterizing materials in small, single-crystal form. And that work recently earned him a big prize: Canfield will receive an Ernest Orlando Lawrence Award on May 21.

CGA announces Leonard Parker Pool Safety Awards

The Compressed Gas Association (CGA) has announced the 2011 Leonard Parker Pool Safety Awards, sponsored by Air Products and Chemicals, Inc.

Cryo Diffusion to provide helium equipment for RasLaffan project in Qatar

SIMES Professor honored for superconductivity research

Steven Kivelson, a member of SLAC’s Stanford Institute for Materials & Energy Science, has been named a winner of the 2012 John Bardeen Prize, in recognition of his theoretical research that has provided significant insights into the nature of “unconventional” superconductors.

Latest in Defining Cryogenics

Adiabatic Demagnetization Refrigeration

Reaching temperatures below 1K requires different techniques than the various helium gas cycles found in large scale refrigeration plants and small cryocoolers. One of these techniques is Adiabatic Demagnetization Refrigeration (ADR). This technique takes advantage of the fact that the entropy of paramagnetic materials in a magnetic field is lower than...

Cryogen-Free

A cryogen is any fluid that operates at cryogenic temperatures (below roughly 150K – 120K). Using this definition, helium gas at 40K is a cryogen. Another more restrictive definition is to use cryogen to refer specifically to liquids at cryogenic temperatures. This is generally how it is used in the...

Cryostats and Cryocoolers

A cryostat is any device designed to maintain things (including fluids) at cryogenic temperatures. In general usage, cryostats tend to be passive devices rather than providing active cooling. In this usage, cryostats keep things cold by thermally isolating them from room temperature. This generally is accomplished by a combination of...

You are encouraged to read Cryo Central’s History...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...

Cryogenic Finishing

The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...
