100 Years of Quantum Is Just the Beginning

Recognizing the importance of quantum science and the need for wider awareness of its past and future impact, dozens of national scientific societies gathered together to support marking 100 years of quantum mechanics with a U.N.-declared international year. The timeline of endorsements for this international year also included the International Union of Pure and...

Cool It Down–Isochoric Preservation

If you’ve ever made the mistake of putting certain fresh fruits or vegetables in the freezer, then you’re already familiar with the effects of freezing on biological tissue. Banana skins turn black and slimy. Whole oranges leak and deflate. Lettuce comes out limp and soggy. The cause of all this...

Advancing Spin Qubit Technology With Cryogenic Probing

In a recent article published in Nature, researchers developed a 300-mm cryogenic probing process to obtain high-volume data on spin qubit devices across full wafers. They optimized an industry-compatible process to fabricate spin qubit devices on a low-disorder host material, enabling automated probing of single electrons in spin qubit arrays across...

HL-LHC’s Cold Powering System Successfully Passed Tests

If you’re an avid follower of High-Luminosity LHC (HL-LHC) news, you will no doubt already have heard about “the python”, the new superconducting link developed at CERN. It is a component of the new cold powering system that will power the HL-LHC inner triplet magnets, which will focus proton beams more...

Why We Still Need a CERN for Climate Change

It was a scorcher last year. Land and sea temperatures were up to 0.2 °C higher every single month in the second half of 2023, with these warm anomalies continuing into 2024. We know the world is warming, but the sudden heat spike had not been predicted. As NASA climate...

New Guide Published: “Select Thermal Properties for Cryogenic Insulation Materials”

Korean Register has published the “Guide to Selection of Thermal Properties of Cryogenic Insulation Materials” for safe storage of cryogenic fuels, including LNG and liquid hydrogen. Last year, the International Maritime Organization (IMO) adopted the ‘2023 Greenhouse Gas Strategy’ with the goal of achieving carbon neutrality in international shipping by 2050....

Transfer Lines

Transfer lines may in some real sense be thought of as the cryogenic fluid analogy of current leads. While current leads carry electrical power to where it’s required in a cryogenic system, transfer lines do the same with cryogenic fluids. Transfer lines range in complexity from very simple U-tubes containing...

Zero Boiloff

Zero Boil Off cryostats are those that contain liquid cryogens but are designed to eliminate or vastly reduce the boil off of  the liquid. These cryostats combine some of the advantages of Cryogen-Free systems (e.g. ease of use and long operational lifetime) with the advantages associated with a reservoir of liquid...

Cryomodule

Cryomodule is a term that is most commonly used to refer to cryostats that contain superconducting radio frequency (SRF) cavities. Such cavities are used to accelerate charged particle beams and are a major component of modern particle accelerators. Using the term cryomodule to refer to cryostats containing SRF cavities appears...

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...
