Stanford Finds Crystal That Could Revolutionize Quantum Tech

Superconductivity and quantum computing have rapidly evolved from theoretical frontiers to real-world technologies. The 2025 Nobel Prize in Physics recognized breakthroughs in superconducting quantum circuits that promise ultra-powerful computing systems. Yet these technologies demand cryogenic operating conditions, near absolute zero, where most materials lose their useful properties. Identifying materials that...

VALCOR ENGINEERING ADDS NEW VIBRATION LABORATORY

Valcor Engineering Corporation, a longtime designer and manufacturer of precision fluid and motion control components—including cryogenic solenoid valves—has expanded its in-house testing resources with the addition of a new Vibration Laboratory at its Springfield, New Jersey headquarters. The new facility provides full 3-axis (X, Y, Z) vibration testing, including sine...

Delta Reliably Meets the Need for Cryogenic Pipe Shoes in the LNG Space

As the LNG industry has grown, so has the number of suppliers who serve that market. No one knows that better, perhaps, than Delta Machine & Ironworks. The Baton Rouge-based fabricator is rapidly becoming the “go to” supplier of one of the most indisputably vital support products on LNG jobsites. Over...

‘Much-loved’ UW collaborator John Clarke wins the Nobel Prize in Physics

  The Royal Swedish Academy of Sciences awarded the 2025 Nobel Prize in Physics jointly to John Clarke, Michel H. Devoret and John M. Martinis, “for the discovery of macroscopic quantum mechanical tunneling and energy quantization in an electric circuit.” Clarke, a professor emeritus of physics at the University of California, Berkeley, collaborates with the Axion Dark...

Stability

Stability refers to the ability of a device employing superconductors to remain in its superconducting state after part of the superconductor transitions back to its normal conducting state due to a disturbance. While the concept can apply to many superconducting devices—transmission lines, generators, motors, etc.—it is most commonly considered in...

Cable-in-Conduit Conductors

Cable-in-Conduit Conductors (CICC) are a common form of superconducting cable used in large-scale applications. There are several varieties of CICCs, but they all consist of many small, stabilized superconducting wires contained within a conduit through which a coolant (typically supercritical He II) flows. Figure 1 shows the cross section of...

Bayonet Coupling

A bayonet coupling is a demountable joint that allows for quick and easy connection and disconnection of cryogenic components, including transfer lines, cryostats, liquefiers and refrigerators. Bayonets provide a number of advantages, chief among them the ability to connect and disconnect the bayonets while components they connect are still at...

Air Separation and Liquefaction

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...

Suppliers of regenerator materials

I was looking for suppliers of regenerator materials. Can you please provide a list of vendors for: • Lead spheres • Bronze screen discs • Rare earth materials and spheres Thank you in advance for any help you can provide.

Containing ice accumulation while recovering helium

We are implementing a system to recover helium from our Janis ST-500 continuous flow LHe cryostat. The recovery system uses standard 1/4″ plastic tubing, which we connect directly to the cryostat’s exhaust port. The problem with this setup is that the gas is still quite cold as it leaves the...
