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.

Liquid Hydrogen

Hydrogen becomes a liquid at 20K and 1 bar. Liquid hydrogen (LH2) is an important substance in industry, transportation and research. Industrial uses of hydrogen include applications in the electronics, glass, chemical and metal processing fields. In these applications, the hydrogen is generally used as a room temperature gas but...

Superconducting Radiofrequency Cavities

Superconducting radio frequency (SRF) cavities represent an important application of cryogenics and superconductivity. SRF cavities are a technology for accelerating charged particle beams via the transfer of radiofrequency (RF) energy to the beams via resonant structures. As such, they are frequently found in large particle accelerators used for scientific research....

Thermal Radiation Shields

Actively cooled thermal radiation shields are a common feature of cryostats whose lowest temperature is less than 77K. These shields, which typically operate at temperatures between that of LN2 and 40K, block thermal radiation from higher temperatures from reaching lower temperature cryogenic components or fluids. Since the heat radiated from...

You are encouraged to read Cryo Central’s History...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...

Cryogenic Finishing

The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...
