US and India Expand Partnership in Search of Neutrinos

Scientists from the United States and India have a long history of scientific collaboration—including the discovery of the top quark— and now US Secretary of Energy Rick Perry and India’s Atomic Energy Secretary Dr. Sekhar Basu have signed an agreement to expand cutting-edge neutrino science projects underway in both countries.

MiniBooNE Probes the Nucleus with Muon Neutrinos

Scientists working on the MiniBooNE experiment at Fermi National Accelerator Laboratory (CSA CSM) report that they were able to identify exactly-known-energy muon neutrinos hitting the atoms at the heart of the particle detector. The result, published in Physical Review Letters, eliminates a major source of uncertainty when testing theoretical models...

UH Scientists Working on Liquid Argon System for Dark Matter Experiment in Italy

The University of Houston is helping to develop technology for DarkSide, a dark matter experiment at Italy's Gran Sasso National Laboratory. The UH team is both upgrading the DarkSide program’s first physics detector and working on an upgrade that will hold 3,800 gallons of liquid argon.

IARPA Moving Forward with SuperTools Project

The Intelligence Advanced Research Projects Activity (IARPA) has announced research contracts for its “SuperTools” program, a multi-year research effort to develop comprehensive software tools for designing and analyzing superconducting electronics circuits.

Physicists Build New Molecules in Ultracold Soup

Using lasers, a team of US and Austrian physicists have coaxed ultracold strontium atoms into complex “Rydberg polarons." The molecules are only stable near absolute zero, where the millikelvin temperatures keep the constituent atoms still long enough to become “glued together” in new, complex structures.

Global Physics Photowalk 2018

Major science laboratories from around the world have announced the 2018 Global Physics Photowalk, a competition open to amateur and professional photographers. For the event, physics facilities in Asia, Australia, Europe and North America will open their doors for a rare opportunity to see behind the scenes of some of...

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...

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?

Using nitrogen as a cryogen

Is it possible to achieve -200˚C using nitrogen as a cryogen?
