Heavy fermions get nuclear boost on way to superconductivity

Physicists from the United States, Germany and China have discovered nuclear effects that help bring about superconductivity in ytterbium dirhodium disilicide (YRS), one of the most-studied materials in a class of quantum critical compounds known as "heavy fermions." The discovery marks the first time that superconductivity has been observed in...

Metamaterials Boost Sensitivity of MRI Machines

A group of researchers from Russia, Australia and the Netherlands have developed a technology that can reduce Magnetic Resonance Imaging (MRI) scanning times by more than 50 percent, allowing hospitals to drastically increase the number of scans without changing equipment. Scientists achieved this leap in efficiency by placing a layer...

Scientists push boundaries of antimatter research in quest for answers

Scientists of the international ALPHA Collaboration have pushed the boundaries of antimatter research with a breakthrough studying the properties of antihydrogen. Published in the journal Nature, the collaboration's result improved the measurement of the charge of antihydrogen, essentially zero, by a factor of 20. The work is the latest contribution...

New Dream Team Leading CERN

Fabiola Gianotti officially began her term as CERN's new—and first female—Director General on January 1, bringing with her a group CERN describes as a "new dream team." Gianotti earned her PhD in experimental particle physics from the University of Milan in 1989 and joined CERN as a researcher in 1994....

Generations of Tesla experts celebrate family reunion at TCC

Experts on superconducting radio frequency technologies (SRF) from all over the world came to the SLAC National Accelerator Laboratory in December for the Tesla Technology Collaboration (TTC) meeting. Akira Yamamoto, Asian director of International Linear Collider (ILC), said the TCC reminded him of a family reunion where everything from technical...

CEC/ICMC 2015 published papers now online and open access

Papers submitted to the 2015 Cryogenic Engineering and International Cryogenic Materials Conferences (CEC-ICMC) are now online. The complete set is available in two volumes, one for each conference, on IOP Science.

Transfer Lines

Transfer lines may in some real sense be thought of as the cryogenic fluid analogy of current leads. While current leads carry electrical power to where it’s required in a cryogenic system, transfer lines do the same with cryogenic fluids. Transfer lines range in complexity from very simple U-tubes containing...

Zero Boiloff

Zero Boil Off cryostats are those that contain liquid cryogens but are designed to eliminate or vastly reduce the boil off of the liquid. These cryostats combine some of the advantages of Cryogen-Free systems (e.g. ease of use and long operational lifetime) with the advantages associated with a reservoir of liquid...

Cryomodule

Cryomodule is a term that is most commonly used to refer to cryostats that contain superconducting radio frequency (SRF) cavities. Such cavities are used to accelerate charged particle beams and are a major component of modern particle accelerators. Using the term cryomodule to refer to cryostats containing SRF cavities appears...

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...
