CSA Supports Science Works

On October 14, CSA participated in the 5th annual Science Works Career Fair at the Museum of Science & Industry in Chicago. Over 200 representatives from more than 40 companies and organizations staffed stations throughout the museum, including Argonne National Laboratory (CSA CSM), Microsoft, Northrop Grumman and even CBS' “Young...

LIGO and Virgo Detect Gravitational Waves Produced by Colliding Neutron Stars

Scientists worldwide reported in October the detection of both gravitational waves—ripples in space and time—and light originating from the spectacular collision of two neutron stars, marking the first time that a cosmic event has been viewed in both gravitational waves and light. The discovery was made beginning on Aug. 17...

2017 Nobel in Physics Celebrates Discovery of Gravitational Waves

The Royal Swedish Academy of Sciences awarded its 2017 Nobel Prize in Physics to Drs. Rainer Weiss, Barry Barish and Kip Thorne, researchers who made decisive contributions to the Laser Interferometer Gravitational-Wave Observatory (LIGO) and its observation of gravitational waves.

Improved Cooling Leads to Rare Achievement in Study of Antimatter

Scientists at CERN are celebrating a rare achievement in precision physics in which collaborators on its BASE experiment measured a property of antimatter 350 times as precisely as it had ever been measured before. The result was accomplished after researchers improved cooling methods for the experiment.

Webb Selfie Focus of Critical Cryogenic Test

What appears to be a unique selfie opportunity was actually a critical photo for the cryogenic testing of NASA’s James Webb Space Telescope in Chamber A at NASA’s Johnson Space Center in Houston. The photo was used to verify the line of sight (the path light will travel) for the...

CUORE Releases First Data Collection

Researchers have released the first collection of data from the full detector of CUORE (Cryogenic Underground Observatory for Rare Events), an experiment considered to be one of the most promising efforts to determine whether tiny elementary particles called neutrinos are identical to their own antiparticles.

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...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...

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...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
