Fermilab Awarded More than $10 million for Quantum Science

The US Department of Energy has awarded scientists at Fermi National Accelerator Laboratory (CSA CSM) more than $10 million to spur research that could revolutionize scientific understanding of nature and the very way it's investigated.

Cryogenic Cooling of Sensing Devices Conference

Cryogenic Cooling of Sensing Devices, a conference sponsored by SPIE, the international professional society for optics and photonics technology, will be held April 14-18, 2019, at the Baltimore Convention Center, Maryland. Conference chairs are Tonny Benschop, Thales Cryogenics B.V. (Netherlands); Sergey V. Riabzev, RICOR Cryogenic & Vacuum Systems (Israel); and...

Staying Chill, Even When Disaster Strikes

When most people prepare for a hurricane, they buy food and water. But when scientist Amanda Moors sees one of those big, red, pinwheel-shaped storms appear on the weather map, she buys liquid nitrogen. Moors spends a lot of time thinking about failure. Not career failure or experiment failure, but...

The ‘Gloo’ Behind James Webb Space Telescope’s Spider Technology

It takes a team of talented individuals working in unison to brainstorm, build and deliver what will become the world’s most powerful space telescope. Marcelino Sansebastian is a Senior Instrument Technician at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, who has been deeply involved with NASA’s James Webb Space...

A Superconductor Story with a Twist

There’s a literal disturbance in the force that alters what physicists have long thought of as a characteristic of superconductivity, according to Rice University scientists. Rice physicists Pengcheng Dai and Andriy Nevidomskyy and their colleagues used simulations and neutron scattering experiments that show the atomic structure of materials to reveal...

Uganda’s First Cryopreservation Unit is Conserving Banana Diversity

Christopher Bendana of Cornell University’s Alliance for Science reports that Uganda’s National Agricultural Research Organization (NARO) is using liquid nitrogen to conserve banana cell lines in a pioneering effort that could help researchers striving to combat disease and climate threats. The science of storing tissues in liquid nitrogen, also commonly...

Helium-3

Helium-3 (3He) is one of the two stable isotopes of helium. The other is the much more common Helium-4 (4He). Neither of these isotopes should be confused with He II, which is the second liquid phase of 4He. He II was discussed in this column in the Spring 2010 edition...

Cryopumping

Cryopumping refers to the use of cryogenic temperatures to produce vacuum in enclosed spaces. More broadly, it can also refer to the removal of gases via cryogenic temperatures from a flow stream or enclosure without necessarily resulting in vacuum pressures. This is an important application of cryogenics and is used...

Thermal Acoustic Oscillations

Thermal Acoustic Oscillations (TAO) are a common event in cryogenic systems that can have significant adverse effects on the performance of the system. TAOs are sustained pressure oscillations that can occur in tubes containing gas, closed at one end (the warm end) that have a very large temperature gradient along...

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...
