Quantum Data Takes a Ride on Sound Waves

Yale scientists have created a device that uses sound waves to store quantum information and convert it from one form to another, all inside a single integrated chip. The device allows a superconducting artificial atom, or qubit, to exchange energy and quantum information with a high-frequency bulk acoustic wave resonator....

FCC and the Superconducting Magnets of the Future

Physicists at CERN are counting on new magnets, ones capable of generating fields of 16 Tesla or more, to increase the energy of its future circular colliders. To achieve these levels, researchers working on CERN's Future Circular Collider (FCC) study have developed a test station known as FRESCA2, a dipole...

Injecting New Life into the LHC

CERN launched the LHC Injectors Upgrade (LIU) project in 2010 to prepare its accelerator complex for the immense challenges of the HL-LHC. Now, in a report appearing in CERN Courier, engineers from the project have provided a status update. In addition to enabling the necessary proton and ion injector chains...

Concrete Applications for Accelerator Science

Particle accelerators are a lot more than simply the engines of particle physics research, according to scientists working on the Accelerator Application Development and Demonstration (A2D2) project at Fermi National Accelerator Laboratory (CSA CSM). Electron beams generated by linear accelerators have all kinds of practical uses, the researchers say, such...

UK commits $88 Million to LBNF/DUNE Project

The United States and United Kingdom have entered into the first-ever umbrella science agreement between the two countries, a move that will see the UK contribute $88 million to the LBNF/DUNE project hosted at Fermi National Accelerator Laboratory (Fermilab, CSA CSM). The funding makes the UK the largest country investing...

IBM Reports Breakthrough in Quantum Computing

Simulating molecules on quantum computers just got easier according to new results obtained with IBM’s superconducting quantum hardware. In an article published in Nature, IBM researchers discuss the implementation of a new quantum algorithm capable of efficiently computing the lowest energy state of small molecules. By mapping the electronic structure...

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...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...

Wind Tunnels

Dr. Robert Kilgore The development of the cryogenic wind tunnel is one of many significant breakthroughs in both cryogenics and wind-tunnel technology made during the past millennium. Interest in the development of high-speed commercial and military aircraft resulted in a review of problems of flow simulation in transonic wind tunnels...

Sealant Adhesive KAE 89?

Can you give me contact details for the manufacturer of a “sealant Adhesive” KAE 89? It is a vapor stop, used on insulation covering LNG carrying conduits. This is a suggested alternative to Foster 90-66. Do you have details of any other alternative products for this application?
