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.

Manufacturers Complete Cryogenic Tank Delivery to ITER

European manufacturers have delivered the last of the 11 cryogenic tanks contracted for the cryoplant at ITER. The manufacturing of all components was undertaken by Air Liquide advanced Technologies (CSA CSM) and its subcontractors, while logistics were handled by DAHER. The ITER fusion machine will require a massive refrigerator to...

Celebrate Dark Matter Day

On October 31, 2017, institutions worldwide will celebrate Dark Matter Day with events highlighting the experiments that could bring us closer to solving the cosmic riddle of dark matter. The Interactions Collaboration, an international community of particle physics communication specialists, is the celebration's sponsor. Information on local events is available...

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

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...

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...
