Breakthrough Quantum Hardware to be Made in USA

Maybell Quantum unveiled the Icebox, a cryogenic platform to power the next generation of quantum computers. Maybell’s condenses a room-sized cryogenic setup into a system slightly larger than a kitchen fridge, cooling quantum devices to just a few thousandths of a degree above absolute zero. Maybell’s Icebox solves several pressing challenges...

JILA Atomic Clocks Measure Einstein’s General Relativity at Millimeter Scale

Physicists from JILA (formerly known as the Joint Institute for Laboratory Astrophysics, a physical science research institute at the University of Colorado Boulder campus and jointly operated by the National Institute of Standards and Technology [NIST] and the University of Colorado Boulder) have measured Albert Einstein’s theory of general relativity...

Ardent Concepts, Inc. Releases High-Density Ganged Coaxial Attenuators to Support Scale-up of Cryogenic and Quantum Computing Applications

Amphenol Ardent Concepts, a leading supplier of ganged coaxial connectors for use in cryogenic environments, has released high-density ganged coaxial attenuators for in-line use with the TR Multicoax™ series to support the many unique challenges of scaling up quantum computing applications for practical use.

Fluoramics Eliminates Harmful Chemicals from Sealants and Lubricants in Cryogenic Pumps

California-based Cryogenic Machinery Corp. (CRYO-MACH) is one of the nation’s leading producers of cryogenic pumps. Founded in 1969, the company manufactures single-stage horizontal centrifugal pumps for many of the world’s largest industrial gas suppliers as well as the leading space exploration companies. According to CRYO-MACH General Manager Zack Swartz, the...

James Webb Telescope in Cooling Process

Cooling things down in space is trickier than it might sound, but that is exactly the process the James Webb telescope is going through right now. Getting down to cryogenic temperature is imperative for its infrared imaging systems to work correctly. While the telescope has already started, it will be...

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...
