HYPRES, a CSA CSM known as the Digital Superconductor Company, has launched Superconducting Energy Efficient Quantum Computing, or SeeQC, a wholly owned subsidiary headquartered in Rome. SeeQC will focus on developing superconducting technologies for a variety of applications, including scalable fault-tolerant quantum computing, quantum communications and quantum simulators. The company...

Cleaning the LHC, Where Air Particles Count as Dirt

Inside the Large Hadron Collider, beams of particles sprint 17 miles around in opposite directions through a pair of evacuated beam pipes. The interior of the pipes needs to be spotless, but it’s not dirt or grime that clogs the LHC—it’s microscopic air molecules.

Cool Pair Plus Expands Distribution Services to Asia

Wincosyn Solution Co., Ltd., of China has selected Cool Pair Plus (CSA CSM) to support its multiple MRI systems, specifically magnet sub-systems, throughout China. Wincosyn Solution is an integrated delivery network of nine independent service companies that provide hospitals turnkey solutions for CT, MRI, and Cath Labs, ECT and linear...

“Bad Metal” Reveals Clues to High-Temperature Superconductivity

A research collaboration based at Stony Brook University has found that “stripes” of electronic charge, which may play a key role in superconductivity, persist across surprisingly high temperatures, shape conductivity and have direction-dependent properties. The findings—published in Physical Review Letters—came as the group studied metals that conduct electricity poorly, looking...

NIST Hybrid Cooler Hits 2 Kelvin

NIST scientists have devised a novel hybrid system for cooling superconducting nanowire single-photon detectors (SNSPD). It uses a pulse-tube refrigerator cooled to 10 K to precool a Joule-Thomson cryocooler that can then reach 2 K. That level of cooling has typically been achieved with liquid helium systems that are costly,...

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...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, 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...

Cryogenic thermophysical property data

I am in search of information regarding cryogenic thermophysical property data, specifically, Thermal Conductivity, Thermal Expansion, Stiffness and Modulus, in the 20K range. My list of materials include: Ti-6AL-4V (ELI), Al 6061-T651, and Invar (36%, plus any other composition which might have data available). Other materials which would be helpful...
