Booster 19 Rolls out to Masseys for Cryogenic Proof Testing

written by Ryan Weber  Following Booster 18’s failure during a pressure test, SpaceX went ahead and set a new record for stacking a booster in the Starship Program, to try and get Block 3 and the program at large back on track. And this weekend, crews rolled Booster 19 out to...

Provaris Delivers on First Phase LCO2 Tank Engineering and Design

By Dominic Ellison  Australian hydrogen and carbon dioxide storage and transport firm Provaris Energy has completed the phase-one delivery of an LCO2 tank front end engineering and design (FEED) program. The programme included detailed engineering and material and weld testing of a 25,000 cbm LCO2 low-pressure tank and class approval with...

New Partnership with Druck set for Major Breakthrough in Hydrogen-Powered Aircraft

The University of Bath has entered a Knowledge Transfer Partnership (KTP) with Druck, a Crane Company business, to develop the world’s first flight-certified cryogenic hydrogen pressure sensor, helping pave the way for net-zero aviation. Hydrogen is one of the most promising solutions to decarbonising air travel, with aviation currently accounting...

In Memoriam: Dr. Ray Radebaugh

It is with deep sadness that we share the passing of Ray Radebaugh. Ray was a pioneer, mentor, and friend whose influence on cryogenics spanned more than five decades and touched nearly every corner of our field. Ray’s passion for engineering began early. Growing up in Mishawaka, Indiana, he learned...

New Cryogenic Vacuum Chamber Cuts Noise for Quantum Ion Trapping

by John Toon, Georgia Institute of Technology Even very slight environmental noise, such as microscopic vibrations or magnetic field fluctuations a hundred times smaller than Earth’s magnetic field, can be catastrophic for quantum computing experiments with trapped ions. To address that challenge, researchers at the Georgia Tech Research Institute (GTRI)...

Remembering Bruce P. Strauss, a Steward of the Superconductivity Community

The superconductivity community has lost one of its most devoted stewards with the passing of Bruce P. Strauss, whose career spanned more than five decades and whose influence reached far beyond his own technical work. Bruce was not only a contributor to applied superconductivity; he was a builder of the...

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...
