ITER’s Magnets Conquer the 4 K Cryostat Challenge

Embarking on the frontiers of innovation, ITER, the International Thermonuclear Experimental Reactor, heralds a new era with its superconducting magnets—a groundbreaking technological marvel designed to operate at an astonishingly low temperature of 4 K (-269 °C), just above absolute zero. ITER’s primary purpose is to explore and demonstrate the potential...

Oxford Cryosystems’ Evolution From Lab to Global Innovation Hub

In the 1980s, John Cosier and Professor Mike Glazier from Oxford University pioneered the creation of an open-flow cooler, initially designed for exclusive use in Oxford University’s Clarendon Laboratory. Its remarkable efficiency quickly gained recognition within the crystallographic community, leading researchers worldwide to seek similar systems. Responding to this demand,...

RIX Liquid Oxygen Generation Plant Supports US Navy’s Newest Aircraft Carriers

Aircraft carriers use highly concentrated gaseous and liquid oxygen for aviation and medical applications. These legacy systems consume large amounts of valuable ship space and require constant attention and adjustment to meet purity and production rates. With the development of USS Gerald R. Ford (CVN-78) – the “first-in-class” nuclear-powered aircraft...

How Lake Shore Cryotronics is Helping Reduce Helium Costs in The Lab

Lake Shore Cryotronics’ Director of Product Management for Cryogenic Systems Rachael Floyd shares how Lake Shore Cryotronics is helping reduce helium costs in the lab. Why is the availability of helium becoming a pressing concern for research labs, and what unique challenges does it pose? The high cost of helium is a big...

Cryo Legacy: Angela Krenn’s Reflections on Cryogenics and Space, a Trailblazer Revisited

In our annual “Women in Cryogenics and Superconductivity” feature, Cold Facts explores the profound contributions of outstanding women in the field. Drawing on its popularity, we wanted to have a candid conversation, reconnecting with a trailblazing woman in cryogenics, previously spotlighted as one of our “Women in Cryogenics.” In this...

New Glenn Completes Initial Cryogenic Testing at Launch Complex 36

Blue Origin continues to take big steps forward with its New Glenn orbital rocket as hardware rolls out to the launch pad, cryogenic testing begins, and the BE-4 engine gains a new test stand. The company still aims to launch New Glenn at least once in 2024. Over the past month,...

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

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...
