Leading Xenon Researchers Unite to Build Next-Generation Dark Matter Detector

The DARWIN and LUX-ZEPLIN collaborations have now joined forces to work together on the design, construction and operation of a new, single, multi-tonne scale xenon observatory to explore dark matter. The announcement was made July 20. The detector will be highly sensitive to a wide range of proposed dark matter...

Cryotherapy System Treats Superficial Bladder Cancer

A minimally invasive cryoablation system offers a novel approach for the treatment of non muscle invasive bladder cancer (NMIBC). The Vessi Medical minimally invasive cryotherapy solution is designed to provide a bladder-specific system that reduces the cost and eliminates complications associated with the current first-line treatment, transurethral resection of bladder...

Supersolidity Enters a Second Dimension

Atoms in a Bose-Einstein condensate (BEC) can exist in a mysterious “supersolid” state in two dimensions, researchers in Austria have shown. The work, which builds on research from 2019 demonstrating supersolidity in one dimension, opens the way to hitherto impossible tests of theoretical predictions about this long-unexplained phenomenon.

How The Ford Motor Company Invented the SQUID

Cooled to a few degrees above absolute zero, a superconducting quantum interference device, or SQUID, can do something amazing: detect a magnetic field only a millionth as strong as the human brain’s, or less than 5 quintillionths of a tesla.

ATLAS Measures Key Higgs Boson Interaction with High Precision

The ATLAS Collaboration has released new measurements of the Higgs-boson decay probability to tau leptons in its four major production modes: gluon fusion (ggF), vector-boson fusion (VBF), the associated production with a W or Z boson (WH, ZH), and the associated production with a top-quark pair (ttH).

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...

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...
