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...

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

Cryogenic Electronics

Randall Kirschman, consulting physicist, Mountain View, California ExtElect@gmail.com Cryogenic electronics—the operation of electronic devices, circuits, and systems at cryogenic temperatures—has been a valuable technology for decades. Cryogenic electronics (also referred to as low-temperature electronics, or cold electronics) can be based on semiconductive devices, on superconductive devices, or on a combination...

Particle Physics: High Energy Physics

Cryogenics and High-Energy Physics 1. From symmetry magazine: http://www.symmetrymagazine.org/cms/?pid=1000627: Cryogenics is the study of how materials behave at temperatures near absolute zero. In high-energy particle accelerators, such frigid temperatures reduce the electrical resistance of wires in superconducting magnets, increasing the magnet strength and allowing faster particle acceleration. The same holds...

HTS Degaussing Systems

From the Spring 2009 issue of Cold Facts (Volume 25, Number 2): Thanks to a joint project by the US Navy and a number of industry partners, high temperature superconducting (HTS) technology is now at the heart of an advanced degaussing system aboard the USS Higgins at the naval station...

Magnetic Resonance Imaging

From http://www.superconductors.org: An area where superconductors can perform a life-saving function is in the field of biomagnetism. Doctors need a non-invasive means of determining what’s going on inside the human body. By impinging a strong superconductor-derived magnetic field into the body, hydrogen atoms that exist in the body’s water and...
