Cold Facts Digital – The go-to place for Cryogenics and Superconductivity

Pre-excavation Work Begins on LBNF/DUNE

An international project to build the largest physics experiment ever constructed in the United States took a major step forward as a new phase of work began at the Sanford Underground Research Facility in South Dakota. When completed entirely, a beam of neutrinos will be sent from Fermi National Accelerator...

Concept Design Released for CERN’s Future Circular Collider

Scientists have for some time been planning the post-LHC world at CERN, especially the Future Circular Collider collaboration. FCC members recently discussed and published options for the future large circular collider and more, mixing advancements in physics together with cost and technical challenges.

Nominations Open Now for Several IEEE Awards

IEEE Council on Superconductivity is currently accepting nominations for many awards, including its Wong Award, Swerdlow Award, Rosner Award and the IEEE Award for Continuing and Significant Contributions in the Field of Applied Superconductivity.

Dark Energy Survey Completes Six-year Mission

The Dark Energy Survey's scientific effort to map a portion of the sky in unprecedented detail has come to an end, but the work to learn more about the expansion of the universe has just begun.

DESY Introduces Astroparticle Physics Research Division

DESY is expanding exploration of the universe with a new research division for astroparticle physics. Such physics has developed rapidly in recent years, according to DESY, and the expansion means the agency will soon have four research divisions, including accelerators, photon science, particle physics and astroparticle physics.

SHI Cryogenics Releases Highest Capacity 4K Cryocooler

The SHI Cryogenics Group (CSA CSM) introduced a new Gifford-McMahon Cryocooler model in January, its highest-capacity 4K cryocooler to date. The advanced cryocooler extends SHI’s existing model range, units already recognized as reliable and versatile systems that feature high cooling capacities, compact designs and orientation-free operation.

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...

Need help comparing chest freezers and upright freezers

Currently we use in our Biobank an upright -80 freezer to store all our samples. We are planning to buy a fully automated bio-repository storage that will do the picking of samples under restricted conditions. But in the meantime I foresee that we have to pick the samples manually. The...

Need recommendations for cryogenic vials

I am looking into standardizing our range of bio storage tubes (cryogenic vials). These will be for both blood and tissue samples and their derivatives. Any recommendations, comments on Micronics, Nalgene, Nunc and or others that are suitable for long term -80 C and -196 C storage, DNA/RNA suitable, would...

We need a custom machine for flash freezing of water

We are an ice making company and have started a new project, which is related to flash freezing of water. It is based on cryogenics technology and we need a custom made machine. I would kindly ask you to pass me a few companies who would be interested in such...

Looking for a pump suitable for cold liquids

I would like to construct a small cooling circuit (appr. 50 x 50 cm) pumping liquid at a temperature down to -120°C from a cold reservoir to the specimen to be cooled. The tubes and connections are not a problem, but does somebody know a pump (suction/compression for circulation) suitable...
