IBM Looks to the Cloud for Quantum Computing

IBM scientists have built a quantum computer system that users can access through the cloud on any desktop or mobile device to run algorithms and experiments. It's called the IBM Quantum Experience and it's powered by quantum processors with five superconducting qubits. Signals are sent in and out of a...

Electrons Trapped in Liquid Helium Show Promise as Quantum Bits

A team of researchers from the University of Chicago, Argonne National Laboratory (CSA CSM) and Yale University has developed a method to trap and manipulate electrons, opening the door for using the particles as quantum bits. Electrons represent an ideal quantum bit, according to the team, with a "spin" that...

NASA Releases Dozens of Patents into Public Domain

NASA has released 56 formerly patented agency technologies into the public domain, making its government developed technologies freely available for unrestricted commercial use. Additionally, a searchable database is also available that catalogs thousands of expired NASA patents already in the public domain.

Cryogenically Cooled Heat Pipes Used for Refrigeration

Scientists at Brunel University London, in collaboration with Air Products PLC, have engineered a new method to build freezers using advanced cryogenically cooled heat pipe technology. The units, capable of reaching temperatures as low as -180 °C, are likely to be used for medical storage, cooling and storing samples ranging...

Fermilab Breaks Ground on Short-Baseline Near Detector Building

Fermilab broke ground on April 27 on the building that will house the future Short-Baseline Near Detector (SBND). The particle detector is one of three that scientists will use to search for the sterile neutrino, a hypothesized particle that scientists say could not only increase understanding for neutrinos already known,...

SVC Partners with ASM International

The Society of Vacuum Coaters (SVC) and ASM International have announced the formation of a strategic alliance designed to bring the complementary strengths of both organizations together to better serve their global members and the community at large. As part of the alliance, ASM will begin providing comprehensive association management...

Adiabatic Demagnetization Refrigeration

Reaching temperatures below 1K requires different techniques than the various helium gas cycles found in large scale refrigeration plants and small cryocoolers. One of these techniques is Adiabatic Demagnetization Refrigeration (ADR). This technique takes advantage of the fact that the entropy of paramagnetic materials in a magnetic field is lower than...

Cryogen-Free

A cryogen is any fluid that operates at cryogenic temperatures (below roughly 150K – 120K). Using this definition, helium gas at 40K is a cryogen. Another more restrictive definition is to use cryogen to refer specifically to liquids at cryogenic temperatures. This is generally how it is used in the...

Cryostats and Cryocoolers

A cryostat is any device designed to maintain things (including fluids) at cryogenic temperatures. In general usage, cryostats tend to be passive devices rather than providing active cooling. In this usage, cryostats keep things cold by thermally isolating them from room temperature. This generally is accomplished by a combination of...

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...

Cryogenic sealant for LNG fueled buses?

Where can I find a cryogenic sealant for my LNG fueled buses?

Material/gel/epoxy to transfer cold temperature of a cryo-box to a test article

I’m on the hunt for a material/gel/epoxy that will transfer the cold temperature of a cryo-box to a test article. The cryo-box is curved and the test article is at the same curvature. I’m looking for something to put between them to make the surface of the test article as...

Manufacture of brazed aluminum heat exchangers: need consultant

I’m seeking a consultant with experience in the manufacture of brazed aluminum heat exchangers for cryogenic applications. Is there anyone you could recommend to me?

Looking for manufacturers of cryogenic dewars with infrared detectors (long wave)

We are looking for manufacturers of cryogenic dewars with infrared detectors (long wave). We need these dewars for repairing infrared systems (thermographic systems) and we cannot find such glass dewars. Do you know any manufacturers’ addresses?
