Scaling Up Cryogenics for Quantum Computing

As we enter 2024, the field of quantum computing continues to develop rapidly. Accessibility to quantum processing and the scaling of systems are key factors in the growing industry. Cloud-based services offer one potential access route to quantum processing, but systems are also being deployed for customers to host on-premises....

‘First-Ever’ Cryogenic Refueling space Mission Announced

Two space infrastructure specialists, Space Machines Company and Spaceium, have joined forces to embark on what they believe to be the first-ever cryogenic refueling space mission in space in 2025. Under terms of a signed agreement, Canada’s Spaceium will integrate its cryogenic storage technology into Space Machine’s platform. Spaceium will then...

Cryogenics Airmen Supply Cool Fuel for Climatic Munition Test

During the intense heat of summer and throughout the humid Florida fall, Airmen donned protective gear to handle, manage, and deliver over 19,000 gallons of liquid nitrogen at temperatures below minus 300 degrees Fahrenheit to support a three-month munition test at Eglin Air Force Base. The 96th Logistics Readiness Squadron’s...

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...

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...

Assistance with resolving a sealing problem?

We are fabricating piping components for refrigeration service. These components must be leak checked at 15 bar (218 psig). We are using a gas test media that is 25% helium and experiencing difficulty on maintaining a seal on the flanged connections. Do you know anyone or any references that could...

Cryogenic data on leather and nomex

Could anyone please help me out with the following cryogenics data: Leather — mechanical properties at 77 K or lower Nomex — thermal conductivity @ 4 to 50 K I lost the data I had some time ago and although this should be easily accessible, I can’t find any reference...
