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. Density, substantial environmental changes, and an increasing need...

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...

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

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...

Seeking recommendations for commercial sensors

I would like to measure vibrations in small LHe cryostats. Could anybody recommend commercial sensors which would be suitable for the purpose? I am interested in the frequency range between 1Hz and a couple of KHz, with particular attention to the low frequency side.

Estimating cost of carbon steel, pure helium storage tanks

In order to perform an indicative cost assessment of our helium cryogenic plant (still in the design phase), I need an estimation of the cost of carbon steel room temperature pure helium storage tanks. The storage pressure is 20 bar. Can anyone give me suggestions about how to estimate the...

Supplier of pressure sensor that works down to 4.2 K

In an actual experiment we would like to measure the static pressure in a cryostat in the range between one and four bar. Therefore we are looking for some (more or less) cheap pressure sensors that work in liquid helium in the pressure range up to five bar. Unfortunately all...

Looking for reference/textbook suggestions

Can you suggest some reference textbooks for practical thermodynamics applications in cryogenic fields? I need textbooks with cryogenics calculations and examples, dimensioning procedures, second principle applications in cryogenics, heat load calculations, cryogenic pump application, etc. Do such books exist? Does any similar source of information exist?
