Development of HTS CORC Cables for High Field Magnets and Advanced Power Transmission

Dr. Danko van der Laan, the 2014 Roger W. Boom awardee, discusses the development of high temperature superconductors (HTS) and their applications in high field magnets and advanced power transmission. He also explains an approach to cable ReBCO tapes called Conductor on Round Core (CORC™) cables, which feature layers of...

Superconductivity record bolstered by magnetic data

Nature reports that scientists in Germany have observed the common molecule hydrogen sulfide superconducting at a record-breaking 203K (-70°C) when subjected to very high pressures. Researchers A. P. Drozdov, M. I. Eremets, I. A. Troyan, V. Ksenofontov and S. I. Shylin report their findings in their paper "Conventional superconductivity at...

JSAP publishes inaugural issue of the JSAP Bulletin

The Japan Society of Applied Physics (JSAP) has published the first issue of the new JSAP Bulletin, a tri-annual online publication designed to highlight JSAP's activities and inspire a global audience engaged in academic and industrial research.

Fermilab Accelerator Division demonstrates Booster Neutrino Beamline operations

After five months of repairing and retooling the Booster Neutrino Beamline (BNB), members of the Accelerator Division at Fermi National Accelerator Laboratory successfully delivered beam to the BNB on June 22. The previous horn, BNB-2, was found to be inoperable in January when it was determined its cooling was no...

Used MRI magnets get a second chance at life in high energy physics experiments

Researchers at the US Department of Energy's Argonne National Laboratory recently acquired two decommissioned magnets from magnetic resonance imaging (MRI) scanners from hospitals in Minnesota and California that will find a new home as proving grounds for instruments used in high energy and nuclear physics experiments. The two new magnets...

Physicist Peter Winter wins DOE Early Career Award

High energy physicist Peter Winter of the US Department of Energy's (DOE) Argonne National Laboratory has received a DOE Early Career Award, a prestigious five-year research grant totaling $2.5 million. The grant will help to fund Winter's contributions to the muon g-2 experiment currently being assembled at Fermi National Accelerator...

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...

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...
