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.

Joule-Thomson Effect

The Joule-Thomson (JT) effect is a thermodynamic process that occurs when a fluid expands from high pressure to low pressure at constant enthalpy (an isenthalpic process). Such a process can be approximated in the real world by expanding a fluid from high pressure to low pressure across a valve. Under...

Current Leads

One of the challenges of using superconducting magnets is the connection of the magnet to a room temperature power supply. This is accomplished via current leads. The trick is that current leads should ideally have a low heat leak, since they connect room temperature to cryogenic temperature, while at the...

Multilayer Insulation

Multilayer insulation (also referred to as superinsulation) is a key component in the reduction of heat leak to cryogenic systems due to thermal radiation. MLI consists of a series of uncooled reflective surfaces placed in the vacuum space between two surfaces, one warmer than the other. Generally speaking, for ideal...

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...

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?

Data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K.

I am looking for data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K. I would appreciate it if someone could give me some hints on where to find it.

Design of cryostats and suspension mechanisms for insulation and cryostat shielding

I’m looking for information about the design of cryostats and suspension mechanisms for insulation and cryostat shielding.
