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...

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”...

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...
