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...

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...

History of Cryogenics

From the Fall 1999 issue of Cold Facts magazine Millennium Breakthroughs A variety of CSA members give different perspectives on the past millennium: What were the most significant breakthroughs in cryogenics during the past millennium? Prof. R.G. Scurlock, Kryos Technology, scurlock@soton.ac.uk (“Breakthrough” = way through obstacles — Oxford English Dictionary)...

Cryobiology

Andreas Sputtek Past President Society for Cryobiology sputtek@uke.uni-hamburg.de or http://www.sputtek.de/. The word cryobiology (from the Greek words “cryo” = cold, “bios” = life, and “logos” = science) literally signifies the science of life at low temperatures. In practice, this field comprises the study of any biological material or system (e.g.,...

Cryogenic Insulation

James E. Fesmire Cryogenics Test Laboratory NASA Kennedy Space Center james.e.fesmire@nasa.gov Introduction In today’s world, the use of cryogenics and low-temperature refrigeration is taking a more and more significant role. From the food industry, transportation, energy, and medical applications to the Space Shuttle, cryogenic liquids must be stored, handled, and...

Presence of alloying elements in tool steels

I want to expand my knowledge of cryogenics in general and tool steels in particular. Specifically, I am keenly interested in learning about the presence of alloying elements in tool steels and how their presence in various combinations affects the performance of tool steels after cryogenic treatment.

Pros and cons of barcoding samples

I was wondering if I could ask for input on pros and cons of barcoding. We are in the process of trying to decide if we should start barcoding our samples and I’m just not sure if this is feasible for our organization. We have numerous sites all over the...
