RIX Cryocooler Tested, Accepted by US Navy for Aircraft Carrier Use

RIX Industries (CSA CSM) announced in August that it had supplied mission-critical cryocooler technology for shipboard pilot and medical applications onboard the USS Gerald R. Ford (CVN-78). The company designs and manufactured a state-of-the-art liquid and gaseous oxygen generating plant that is now used onboard the ship.

Berkeley Lab Scientists Contribute to New Exploration of Higgs Boson Interactions

Since the discovery of the Higgs boson in 2012 based on data from the ATLAS and CMS experiments at CERN’s Large Hadron Collider, scientists have been gathering new data on the Higgs particle and its associated Higgs field to understand how—and whether—it interacts with specific types of other particles. Released...

NASA’s SOFIA Discovers Water on Sunlit Surface of Moon

Announced on October 26, NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) has confirmed, for the first time, water on the sunlit surface of the Moon. This discovery indicates that water may be distributed across the lunar surface, and not limited to cold, shadowed places.

Quirky Response to Magnetism Presents Quantum Physics Mystery

The search is on to discover new states of matter, and possibly new ways of encoding, manipulating and transporting information. One goal is to harness materials’ quantum properties for communications that go beyond what’s possible with conventional electronics. Topological insulators—materials that act mostly as insulators but carry electric current across...

Instant Systems Promotes Best Practices for Cryogenic Packaging Selection

Elizabeth Beck of Instant Systems (CSA CSM), a leading supplier of cryogenics packaging solutions, outlines the three key attributes to keep in mind when selecting the most suitable flexible packaging for a particular cryogenic application.

XENON1T Dark Matter Experiment Detects Unexplained Excess Events, Prepares Upgrades

Scientists from the international XENON collaboration announced on June 17 that data from their XENON1T detector, the world’s most sensitive dark matter experiment, shows a surprising excess of events. These events may suggest the existence of a new particle known as the solar axion or indicate previously unknown properties of...

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...

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...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
