Ten Ways Fermilab Advanced Science and Technology in 2020

More than 3,500 researchers from around the world collaborate with the US Department of Energy’s Fermi National Accelerator Laboratory (CSA CSM) to develop state-of-the-art technologies and solve the mysteries of matter, energy, space and time. Here is a look at 10 ways Fermilab advanced science and technology in 2020.

Simulating Subatomic Physics on a Quantum Computer

When two heavy ions collide inside a particle accelerator, they produce a near-perfect fluid through which an assortment of fundamental particles swim. For scientists to accurately simulate even a tiny drop of this hot and dense subatomic brew with a classical computer, it would take longer than the age of...

Manchester Group Discovers New Family of Quasiparticles in Graphene-Based Materials

A group of researchers led by Sir Andre Geim and Dr Alexey Berdyugin at the UK University of Manchester have discovered and characterized a new family of quasiparticles named "Brown-Zak fermions" in graphene-based superlattices. The study follows years of successive advances in graphene-boron nitride superlattices which allowed the observation of...

Preparatory ‘Pre-lab’ Proposed for ILC

On September 10, the International Committee for Future Accelerators announced the structure and members of a new organizational team to prepare a “pre-laboratory” for an International Linear Collider in Japan. The ILC International Development Team, which consists of an executive board and three working groups—governing the pre-lab setup, accelerator, physics...

REBCO HTS Wire Manufacturer SuperPower Relocates to New Facility

On August 24, SuperPower Inc. (CSA CSM), a wholly owned subsidiary of Japan’s Furukawa Electric Company, Ltd., announced that it has completed its move and is now operating from a new facility in Glenville NY. The company is a world leader for the development and manufacturing of REBCO-based second generation...

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

Air Separation and Liquefaction

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...

Suppliers of regenerator materials

I was looking for suppliers of regenerator materials. Can you please provide a list of vendors for: • Lead spheres • Bronze screen discs • Rare earth materials and spheres Thank you in advance for any help you can provide.

Containing ice accumulation while recovering helium

We are implementing a system to recover helium from our Janis ST-500 continuous flow LHe cryostat. The recovery system uses standard 1/4″ plastic tubing, which we connect directly to the cryostat’s exhaust port. The problem with this setup is that the gas is still quite cold as it leaves the...
