NCSU researchers tackle problem facing next-generation YBCO superconductors

Researchers from North Carolina State University have developed a new computational approach to improve the utility of superconductive materials for specific design applications – and have used the approach to solve a key research obstacle for the next-generation superconductor material yttrium barium copper oxide (YBCO).

NHMFL reaches new world record in magnetic field generation

A research team at the National High Magnetic Field Laboratory, a CSA Corporate Sustaining Member, has reached a new world record in magnetic field generation, successfully testing a superconducting electromagnet to a field of 35.4 tesla.

US Marine Corps uses cryogenics for training, service

An F/A-18 Hornet flies overhead, trailing its target at sub-sonic speeds. The pilot’s breath is quick and sharp as he gets close to hearing the lock tone over the image of his evading opponent.

Energy Recovery Linac (ERL) reaches milestones

Cornell scientists have surpassed two major scientific milestones toward proving the technology of a novel, exceedingly powerful X-ray source.

MicroBooNE receives third-stage approval from DOE

Fermilab is now part of the recent buzz about neutrinos following the CERN announcement that neutrinos sent to INFN in Italy may have traveled faster than the speed of light: the MicroBooNE neutrino experiment at Fermilab has received Critical Decision 2-3a approval from the Department of Energy.

Brookhaven National Lab named an APS Historic Site

The American Physical Society (APS) — a 48,000-member organization representing physicists in the United States and around the world and publisher of numerous scientific journals — has named Brookhaven National Laboratory an APS Historic Site.

Liquid Hydrogen

Hydrogen becomes a liquid at 20K and 1 bar. Liquid hydrogen (LH2) is an important substance in industry, transportation and research. Industrial uses of hydrogen include applications in the electronics, glass, chemical and metal processing fields. In these applications, the hydrogen is generally used as a room temperature gas but...

Superconducting Radiofrequency Cavities

Superconducting radio frequency (SRF) cavities represent an important application of cryogenics and superconductivity. SRF cavities are a technology for accelerating charged particle beams via the transfer of radiofrequency (RF) energy to the beams via resonant structures. As such, they are frequently found in large particle accelerators used for scientific research....

Thermal Radiation Shields

Actively cooled thermal radiation shields are a common feature of cryostats whose lowest temperature is less than 77K. These shields, which typically operate at temperatures between that of LN2 and 40K, block thermal radiation from higher temperatures from reaching lower temperature cryogenic components or fluids. Since the heat radiated from...

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...

Information on how the emissivity of the panel changes with air fouling?

I work at a facility with a large thermal vacuum chamber. We are using both nitrogen and helium shrouds.

In search of a calculation for designing a cryostat

I am a final year physics student at the University of Birmingham, and as part of a group I am currently designing a cryostat. One of the calculations I need to make (very soon!) is how much heat will be conducted down the walls. All information I have found so...

Safety of ethylene glycol and pressurized oxygen

We are reviewing the product design of liquid filled differential level gauges and want to insure that they meet the industry requirements. The former license owner had authorized that a fill fluid of ethylene glycol (68%) and distilled water (32%) could be used for oxygen service up to 500 psi....
