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...

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...

Seeking alloy that keeps elastic property down to 10K

I am looking for a metal (alloy) that supports high temperatures (at least 1600K) and keeps its elastic property at low temperatures down to 10K. Rhenium is a good one because it does not become brittle. But it is quite expensive. Pure tungsten and molybdenum enter in the brittle regime...

Searching for a freezer that does not need electricity

I’m student of University of Barcelona. We do technical cryogenic research and we are searching for a cryogenic portable freezer that does not need electricity. We can’t find any company that offers something like this. The product we are looking for is the typical portable freezer for food or drinks...

FEP Encapsulated O rings in the cryogenic process

Can you please advise if FEP Encapsulated O rings are used within the cryogenic process and what materials? I have been asked by my company to write about FEP Encapsulated O rings for a training seminar.

Need material property data for polycrystalline / sintered ceramics

I am a ME grad student currently working on the design of a detector array / focal plate of a scientific space instrument operating at a temperature of about -80…-100°C. Although this is not in the cryogenic temperature range, I would like to address two questions to you as the...
