LCLS X-ray Laser Reveals Ultrafast Riboswitch in Action

Scientists have used the powerful X-ray laser at the Linac Coherent Light Source (LCLS), located at the Department of Energy’s SLAC National Accelerator Laboratory, to take the first ever snapshots of an ultrafast riboswitch, a gene regulator that can switch individual genes on and off. According to the research team,...

Stanford Study Suggests Battery Power Will Trump Hydrogen Fuel Cells

Stanford researchers say communities would be better off investing in electric vehicles that run on batteries instead of hydrogen fuel cells, in part because a hydrogen infrastructure provides few additional energy benefits for communities beyond clean transportation.

CoEPP and IHEP to Collaborate on Future Experiments

At a ceremony held Nov. 8 in Beijing, representatives from the ARC Center for Particle Physics at the Terascale (CoEPP) and the Institute of High Energy Physics (IHEP) signed a Memorandum of Understanding to establish scientific exchange, collaboration and cooperation between the two organizations.

Cooling Technique Improves Antiproton Mass Measurement

Scientists from CERN's ASACUSA experiment have announced a new precision measurement of the mass of the antiproton relative to that of the electron, a result based on spectroscopic measurements of approximately two billion antiprotonic helium atoms cooled to temperatures near absolute zero.

ASC 2016 Highlights Progress in Superconductivity

Over 1,600 researchers and engineers from 36 countries gathered in Denver September 4-9 for ASC 2016, attending plenaries, poster sessions and meetings under the watchful gaze of the Colorado Convention Center’s Blue Bear. Celebrating its 50th year, the conference covered a wide range of topics, from superconducting electronics detectors and...

2016 ASC Best Student Paper Contest

The Applied Superconductivity Conference's Best Student Paper Contest recognizes outstanding presentations made at ASC by full-time students. The ability to describe one’s research, by succinctly capturing key results and ideas in written form as well as by presenting and defending the work in front of an audience of experts, is...

Stability

Stability refers to the ability of a device employing superconductors to remain in its superconducting state after part of the superconductor transitions back to its normal conducting state due to a disturbance. While the concept can apply to many superconducting devices—transmission lines, generators, motors, etc.—it is most commonly considered in...

Cable-in-Conduit Conductors

Cable-in-Conduit Conductors (CICC) are a common form of superconducting cable used in large-scale applications. There are several varieties of CICCs, but they all consist of many small, stabilized superconducting wires contained within a conduit through which a coolant (typically supercritical He II) flows. Figure 1 shows the cross section of...

Bayonet Coupling

A bayonet coupling is a demountable joint that allows for quick and easy connection and disconnection of cryogenic components, including transfer lines, cryostats, liquefiers and refrigerators. Bayonets provide a number of advantages, chief among them the ability to connect and disconnect the bayonets while components they connect are still at...

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...

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...
