Manchester Group Discovers New Family of Quasiparticles in Graphene-Based Materials

A group of researchers led by Sir Andre Geim and Dr Alexey Berdyugin at the UK University of Manchester have discovered and characterized a new family of quasiparticles named "Brown-Zak fermions" in graphene-based superlattices. The study follows years of successive advances in graphene-boron nitride superlattices which allowed the observation of...

Preparatory ‘Pre-lab’ Proposed for ILC

On September 10, the International Committee for Future Accelerators announced the structure and members of a new organizational team to prepare a “pre-laboratory” for an International Linear Collider in Japan. The ILC International Development Team, which consists of an executive board and three working groups—governing the pre-lab setup, accelerator, physics...

REBCO HTS Wire Manufacturer SuperPower Relocates to New Facility

On August 24, SuperPower Inc. (CSA CSM), a wholly owned subsidiary of Japan’s Furukawa Electric Company, Ltd., announced that it has completed its move and is now operating from a new facility in Glenville NY. The company is a world leader for the development and manufacturing of REBCO-based second generation...

Cryogenics Contributes to Lifesaving Pandemic Treatments, Research

For the past seven months, the US has been fighting alongside the rest of the world to reign in COVID-19. From cutting-edge research and technical developments to recovery routines and last-line-of-defense treatments, cryogenics has played a number of roles—some expected and some surprising—to aid in the international response to the...

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...
