EASITrain to Hire, Fund PhD Candidates in Superconductivity and Related Fields

CERN has announced its European Advanced Superconductivity Innovation and Training project (EASITrain), a four-year initiative that brings together leading research institutes and industrial partners to train the next generation of researchers. It will cover the development of 15 Early Stage Researchers (ESRs) on projects related to superconducting wires, superconducting thin...

Electronic Symmetry Breaking Common in Superconducting Materials in High Magnetic Fields

Researchers from the Los Alamos National Laboratory report that the phenomenon of electronic symmetry breaking is common in superconducting materials in high magnetic fields. Using transport measurements near the field-tuned quantum critical point of CeRhIn5 at 50 Tesla, the researchers observed a fluctuating nematic-like state in which the material’s electrons...

UA Researchers to Design New Cryogenic Focal Plane Arrays

The American Institute for Manufacturing Integrated Photonics (AIM Photonics), a public-private partnership advancing the nation’s photonics manufacturing capabilities, has chosen a University of Arizona research team to design, fabricate and test new PIC-based datalinks for cryogenic focal plane array (FPA) readout. The project, according to AIM Photonics, has the potential...

SQUID Detector Reaches New Sensitivity Levels

Investigators at the University of Colorado, Boulder, and the National Institute of Standards and Technology (NIST) have developed a new sensor-array-based instrument that offers ultralow noise detection of small amounts of energy for a number of applications. The new device permits the collection of data from many more detectors than...

NASA Readies Multiple Balloon Program Experiments

NASA's balloon program is currently preparing new missions bearing sensitive instruments, including one designed to investigate the birth of our universe and another with ballooning origins that will fly on the International Space Station.

ICARUS Arrives at Fermilab, Greeted by Familiar Face

The ICARUS detector ended its journey across the Atlantic on July 26, arriving by semi-truck at the Fermi National Accelerator Laboratory. Waiting for it there was Angela Fava, an experimental physicist who first worked with the machine in 2006, tightening bolts and connecting cables while an undergrad in Italy. In...

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...

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...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
