Fermilab Using ArgoNeuT Data to Advance Future Measurement of Neutrinos in Liquid Argon

Scientists at Fermi National Accelerator Laboratory (CSA CSM) have continued to analyze data from the retired ArgoNeuT neutrino detector, developing processes to improve future simulations and software that finds particles in liquid-argon based neutrino detectors.

Cryoforce Spectroscopy Reveals DNA Mechanical Properties

Physicists from the University of Basel have developed a low temperature method to examine the elasticity and binding properties of DNA molecules. The process utilized cryoforce spectroscopy and computer simulations, a combination that revealed DNA molecules behaving like a chain of small coil springs.

CAL Performing Coolest Experiments in the Universe

NASA's Cold Atom Lab (CAL) is the first facility inside the International Space Station to produce clouds of "ultracold" atoms that can reach a fraction of a degree above absolute zero.

New Theory Sends Kelvin Temperature Below Current Low

A recent collaboration of researchers has shown that it is possible, in principle, to measure temperatures below a billionth of a kelvin without significantly disturbing the Bose-Einstein condensate used in the study.

Pre-excavation Work Begins on LBNF/DUNE

An international project to build the largest physics experiment ever constructed in the United States took a major step forward as a new phase of work began at the Sanford Underground Research Facility in South Dakota. When completed entirely, a beam of neutrinos will be sent from Fermi National Accelerator...

Concept Design Released for CERN’s Future Circular Collider

Scientists have for some time been planning the post-LHC world at CERN, especially the Future Circular Collider collaboration. FCC members recently discussed and published options for the future large circular collider and more, mixing advancements in physics together with cost and technical challenges.

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...

Resistance to embrittlement at low temperatures

Could anyone advise me about resistance to embrittlement at low temperatures for the alloys in subject, i.e. does the CF10M perform like the CF8M in the same cryogenic service (-215F)? Amara Maafi Amara.Maafi@bg-group.com

Need help with temperature dependent model

I am a fourth-year student at New Zealand University. My name is Xu Ke. I have a project to generate a temperature dependent model for inductor, capacitor and diode by using PLECS. PLECS is software which acts as a toolbox for MATLAB. In my models, the temperature is very low,...

In what form is water available in LN2?

Does anybody know in what form water is available in LN2? There probably is a block of ice in the bottom of the tank. But as water comes in many shapes, I can imagine snow or crystals floating free in the LN2. When water is available in LN2, could small...

Separating gases using cryogenics

We are looking for some consulting engineers who understand how to separate gases using cryogenics. We have a new process which takes biomass and converts it to 5 gases and we need to separate these gases into their pure forms. Thanks for your help. Malcolm Draper Energy Research Group LLC...
