First results from LHC Run 2 presented in Vienna

The world particle physics community convened in Vienna from July 22-29 for the 2015 European Physical Society Conference on High Energy Physics, where the latest results in the field were presented and discussed, including the first results from Run 2 of the Large Hadron Collider (LHC) at CERN. This was...

IceCube sees highest-energy neutrino ever found

On August 4, scientists working on the IceCube neutrino experiment at the South Pole reported the observation of a neutrino event that had an energy of more than 2000 trillion electron volts, making it the highest energy neutrino event ever found. The event offers scientists the best hope yet that...

UCLA scientists use large particle accelerator to visualize properties of nanoscale electronic materials

Using the large TRIUMF cyclotron in Vancouver, British Columbia, UCLA researchers have developed a new method to visualize topological insulators, a class of materials that could lead to improved performance in spintronics, at the nanoscale. The new method is the first use of beta-detected nuclear magnetic resonance to study the...

Nonmagnetic elements form unique magnet

Scientists at Rice University combined titanium and gold to make an itinerant antiferromagnetic metal, TiAu, from nonmagnetic constituent elements. While the uses for this particular magnet have yet to be determined, this discovery could enhance the scientific understanding of magnetism.

CERN’s LHCb experiment reports observation of exotic pentaquark particles

On July 14, the LHCb experiment at CERN's Large Hadron Collider reported the discovery of a class of particles known as pentaquarks, which are composed of four quarks and an antiquark. The collaboration has submitted a paper reporting these findings to the journal Physical Review Letters.

Fermilab’s flagship accelerator sets world record

On July 8, scientists announced that the US Department of Energy's Fermi National Accelerator Laboratory (Fermilab, CSA CSM) set a world record for the most powerful high-energy particle beam for neutrino experiments: a sustained 521-kilowatt beam generated by the Main Injector particle accelerator. More than 1,000 physicists from around 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...

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...
