Foundations of Cryocoolers Virtual Webinars

Plan now to join us for this in-depth exploration of all things cryocoolers! Normally presented in conjunction with the International Cryocooler Conference, the educational and experience-based Foundations of Cryocoolers Short Course is moving online with ICC. Perfect for cryogenic veterans and students alike, this online course will provide an invaluable...

ICCRT Postponed to 2021

Following restrictions imposed by Romanian Government to limit Covid19 outbreaks, including guidelines for organized indoor events, organizers of the International Conference on Cryocooler and Refrigeration Technologies were unfortunately constrained and made the decision to postpone the conference originally planned for October 7-10, 2020, in Bucharest to next year—the exact date...

Super-Kamiokande Gets an Upgrade to Detect Neutrinos from Ancient Supernovae

Buried 1-kilometer underground near the city of Hida, Japan, is a 40-meter tall cylinder filled with 50 million liters of water—the Super-Kamiokande neutrino observatory. Since 1996, it has been observing neutrinos—subatomic particles—from solar, extrasolar, terrestrial and artificial sources with highly sensitive optical sensors which record minute flashes of light that...

ASC to Hold All-virtual Conference October 24-November 7

The 2020 Applied Superconductivity Conference (ASC) will be held virtually over two weeks beginning October 24 and will offer a combined virtual platform for plenary, oral and poster presentations, a conference exhibition, a new program for young professionals called ELEVATE, virtual breakouts, coffee breaks and other features.

A Quantum Thermometer to Measure the Coldest Temperatures in the Universe

On August 20, Trinity College Dublin announced that physicists from the college have proposed a thermometer based on quantum entanglement that can accurately measure temperatures a billion times colder than those in outer space. These ultracold temperatures arise in clouds of atoms, known as Fermi gases, which are created by...

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...

What is the temperature range of cryogenics?

Could you please tell me what is the temperature range of cryogenics? In other words, is -100°F considered cryogenic, or does it start lower? Could I expect to see some extended life in D2 stamping dies? What would the recipe be to achieve the desired results using cryogenics?
