Building Hubble’s successor: crucial Pathfinder test set up inside Chamber A

Inside the giant thermal vacuum chamber, called Chamber A, at NASA's Johnson Space Center in Houston, the James Webb Space Telescope's Pathfinder backplane test model is being prepared for its cryogenic test.

New physics unlocks the mechanism of the Kondo Effect

Researchers have made an experimental breakthrough in explaining a rare property of an exotic magnetic material, potentially opening a path to a host of new technologies. The work, led by Brookhaven National Laboratory physicist Ignace Jarrige and University of Connecticut professor Jason Hancock, together with collaborators at the Argonne National...

ICARUS neutrino experiment to move to Fermilab

A group of scientists led by Nobel laureate Carlo Rubbia will transport the world’s largest liquid-argon neutrino detector across the Atlantic Ocean from CERN to its new home at the US Department of Energy’s Fermi National Accelerator Laboratory. When it arrives at Fermilab, the detector will become part of an...

Mu2e breaks ground on experiment seeking new physics

Members of the Mu2e collaboration recently dug their shovels into the ground of Fermilab's Muon Campus for the experiment that will search for the direct conversion of a muon into an electron in the hunt for new physics.

HEPTech: where academia meets industry

The high energy physics technology transfer network, or HEPTech, aims to bring together leading European high energy physics research institutions to provide academics and industry with a single point of access to the skills, capabilities, technologies and R&D opportunities of the high energy physics community in a highly collaborative open-science...

Elsevier’s new open access journal Heliyon now accepting submissions

Elsevier has announced the call for submissions for its new open access journal Heliyon. The journal will be a publishing platform for sound research developed in collaboration with the research community so as to offer researchers a new publishing option tailored to their needs.

Dilution Refrigerators

Dilution refrigerators are a common technique for reaching temperatures below 1K, particularly where continuous cooling at these temperatures is required. Helium exists in two stable isotopes: 4He and 3He. Naturally occurring 3He is extremely rare, constituting less than 1 part per million of helium gas. However, 3He can be manufactured,...

Oxygen Deficiency Hazards

Oxygen Deficiency Hazards (ODH) are a significant safety issue in cryogenic facilities. ODH occurs when inert gases such as nitrogen, helium or argon displace room air and thus lower the percentage of oxygen in the space below that required for human life. OSHA defines an area as oxygen deficient if...

Kelvin Temperature Scale

The Kelvin temperature scale is the principal temperature scale used in cryogenics and science. The kelvin is also one of the seven base units in the Système International d’Unités (SI) and is the unit of thermodynamic temperature. Thermodynamic temperature is a fundamental physical quantity (like mass, length or electrical current)...

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...
