New X-ray laser technique could reveal atomic detail of proteins

Use of the Linac Coherent Light Source has led to the development of a unique X-ray laser innovation at the Department of Energy's SLAC National Accelerator Laboratory that may make it easier and faster for scientists to fully map medically important proteins whose structures have remained stubbornly out of reach.

Restoring the Foundation: The Vital Role of Research in Preserving the American Dream

“Restoring the Foundation: The Vital Role of Research in Preserving the American Dream,” a 154-page report released by the American Academy of Arts and Science, reinforces many of the findings and recommendations of the 2005 report “Rising Above the Gathering Storm.” The earlier report focused on the causes of America’s...

Boom Awardees Making Headlines

The Cryogenic Society of America is very proud of the recipients of our Roger W. Boom Award. Over the years since 1996, we have watched as our awardees have moved ahead in their fields, living up to the promise the Boom awards committee saw in them. We caught up with...

Frozen Aliens and Superpowers

Liquid nitrogen is cool. That’s a classic pun, but it’s also true. Liquid nitrogen is dramatic and a little bit dangerous, and its startling effects on everyday objects are immediate, making it a fantastic tool for science education and outreach.

LHC experiments join forces to zoom in on the Higgs boson

For the first time, CERN's ATLAS and CMS have presented a combination of their results on the mass of the Higgs boson--on March 17, 2015, during the 50th session of “Rencontres de Moriond” in La Thuile Italy. The combined mass of the Higgs boson corresponds to a measurement precision of...

Neutrons provide first images of refrigerant flow

Using noninvasive techniques, researchers at DOE's Oak Ridge National Laboratory have captured undistorted snapshots of refrigerants flowing through small heat exchangers, helping to further elucidate characteristics of heat transfer.

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...

Air Separation and Liquefaction

by Nils Tellier, PE, President, EPSIM Corporation (CSA CSM) nils@epsim.us All illustrations courtesy EPSIM Corporation Background History of Air Separation and Liquefaction This section builds on a rich history of methods to develop deep refrigeration and cryogenic liquefaction during the 19th Century. 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...

TS diagram for helium

Where can I obtain a really big, nice TS diagram for helium ?

Reliability and mounting of electronic substrates at low temperatures

I am currently working on the design of a focal plane assembly to be implemented on a small satellite (4 EMCCD detectors) to be operated at -80°C (which is not really cryogenic and likely still considered boiling hot for most of you :-). As it is passively cooled, the assembly...

Are 3D drawings included in the sale of a cryogenic plant?

I have a question concerning the 3D drawings of a cryogenic plant. The integration of the 3D drawings of a plant with the 3D main model of a new laboratory or a new facility can be a complex work that takes a lot of time. I would like to know...

Looking for a source of LOX impact testing to ASTM D2512

I have been looking for a source of LOX impact testing to ASTM D2512. I am aware of NASA and White Sands, but am looking for a commercial entity doing the work. No luck so far, even calling a lot of the folks on the CSA website. Any referrals will...
