NASA on Track for Future Missions with Initial Artemis II Assessments

Following NASA’s Artemis II mission successfully splashing down on Earth, engineers started diving into detailed analysis of data to assess how key systems and subsystems on the Orion spacecraft, SLS (Space Launch System) rocket, and systems at the launch pad at the agency’s Kennedy Space Center in Florida performed. The...

Muon g-2 Experiment Pioneers Win Breakthrough Prize in Fundamental Physics

The Muon g-2 Collaborations at CERN — the European Organization for Nuclear Research — and two U.S. Department of Energy National Laboratories — Brookhaven National Laboratory and Fermi National Accelerator Laboratory (Fermilab) — are the recipients of this year’s Breakthrough Prize in Fundamental Physics. Over a period of more than 60 years,...

Call for Photo Submissions: Support the AIP Visual Archives

AIP is working to enrich Niels Bohr Library & Archives collections by improving the documentation of women and underrepresented people in the physical sciences. They collect visual documentation of the personal and professional lives of physical scientists. Their collection contains images of modern American physicists, astronomers, geophysicists and many other kinds of scientists. In general, they...

BASE Experiment at CERN Succeeds in Transporting Antimatter

Today, in a world first, a team of scientists from the BASE experiment at CERN successfully transported a trap filled with antiprotons in a truck across the Laboratory’s main site. The team managed to accumulate a cloud of 92 antiprotons in an innovative portable cryogenic Penning trap, then disconnect it from the...

By Phillipp Bircher With the appointment of Dr. Barbara Frei-Spreiter, RUAG International concludes the multi-stage search process to succeed André Wall as CEO of RUAG International and its space business, Beyond Gravity. Dr. Barbara Frei-Spreiter is a proven Swiss executive with over 25 years of international leadership experience in global...

Solving a Mystery in Dark Matter Detectors Could Improve Quantum Computers

By Lauren Biron Although dark matter makes up most of the mass in our universe, it has never been directly observed. To hunt for lighter dark matter and other rare phenomena, researchers must solve a puzzle in their supersensitive detectors: an unexpected number of low-energy events, called the “low-energy excess”...

Latest in Defining Cryogenics

Refrigerators and Liquefiers

Two of the most common terms used in cryogenics are “refrigerator” and “liquefier.” These terms describe similar and, as will be seen, in some cases identical components. A refrigerator provides cooling (that is, absorbs heat) at cryogenic temperatures. Refrigerators typically put a working fluid (such as helium) through one of...

Air Separation

Air separation is one of the largest, as well as earliest, industrial applications of cryogenics. In this process, cryogenic temperatures are used to separate air into its constituent gases: nitrogen (78.08%), oxygen (20.95%), argon (0.93%) and carbon dioxide (0.3%). Trace gases such as krypton, neon, xenon and helium total far...

Coefficient of Performance and Figure of Merit

The coefficient of performance (COP) is used to describe the effectiveness of refrigerators, including those operating at cryogenic temperatures. The COP is defined as the amount of heat removed at the cryogenic operating temperature of the refrigerator divided by the amount of work that must be applied to remove the...

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...

Definition or max temp which defines “cryogenic”?

Please help me with a definition: I am calculating material and fabrication costs for a quote for a hydrocarbon meter station.

Thermal shock on steel cylinder when dropped into liquid nitrogen

We are a research team at the University of South Florida, studying the “thermal shock” on a steel cylinder when it is dropped into liquid nitrogen. We want to make sure that the thermocouple does not get influenced by the surrounding LN2. Any advice?

Getter materials to absorb out gassed materials?

Here’s one for the scientists: We would like to sell vacuum insulated pipe for high temperature fluid applications. Are there any good getter materials that we can place in the vacuum space of our VJP to absorb outgassed materials at elevated temperatures?

Data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K.

I am looking for data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K. I would appreciate it if someone could give me some hints on where to find it.
