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...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

Thermal shock on steel cylinder when dropped into liquid nitrogen

We are a research team at the University of South Florida, studying the “thermal shock” on a steel cylinder when it is dropped into liquid nitrogen. We want to make sure that the thermocouple does not get influenced by the surrounding LN2. Any advice?

Getter materials to absorb out gassed materials?

Here’s one for the scientists: We would like to sell vacuum insulated pipe for high temperature fluid applications. Are there any good getter materials that we can place in the vacuum space of our VJP to absorb outgassed materials at elevated temperatures?
