NASA Introduces WFIRST, a “Wider Set of Eyes” on the Universe

After years of preparatory studies, NASA is formally starting an astrophysics mission designed to help unlock the secrets of the universe—the Wide Field Infrared Survey Telescope (WFIRST). With a view 100 times bigger than that of NASA’s Hubble Space Telescope, WFIRST will survey large regions of the sky in near-infrared...

Gravitational Waves Detected 100 Years after Einstein’s Prediction

Scientists have for the first time observed ripples in the fabric of spacetime called gravitational waves, confirming a major prediction of Albert Einstein’s 1915 general theory of relativity and opening an unprecedented new window onto the cosmos. The discovery was made possible by the enhanced capabilities of Advanced LIGO, a...

Researchers Designing Safer Cryotherapy Devices

Researchers at the University of Texas at Arlington and the University of Texas at Austin are developing a state-of-the-art cryotherapy device, one that can stimulate blood flow to keep tissue healthy and minimize potential side effects, and what are believed to be the first formal protocols for effective and safe...

The Rothman Institute has nominated Cryofab (CSA CSM), a manufacturer of cryogenic equipment, for New Jersey Family Business of the Year for 2015, recognizing the company's impact on the community and its perseverance, business success and commitment to family.

1st Asian ICMC and CSSJ 50th Anniversary Conference

ICMC (International Cryogenic Materials Conference) and CSSJ (Cryogenics and Superconductivity Society of Japan) have announced a new joint conference to be held during November 2016 in Kanazawa, Japan. Contributed, invited and plenary papers on a wide range of topics will be presented, including superconducting materials, wire, tapes and electronics; low-temperature...

Neutrinos on a Seesaw

Mass is a fundamental property of matter, but there’s still a lot about it we don’t understand—especially when it comes to the tiny masses of neutrinos. An idea called the seesaw mechanism proposes a way to explain the masses of these curious particles. If shown to be correct, it could...

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...

Need help with calculating flow rate

I have to maintain a certain mass (some tons) at 100 K by circulating in it GHe (through apposite channels). How can I calculate the flow rate needed? I suppose that the delta T (T inlet and T outlet) and the heat load on the mass are necessary. Knowing the...
