Beam Delivered to Muon g-2, First Results Expected Later this Year

Accelerators at the Fermi National Accelerator Laboratory (CSA CSM) have delivered beam to the Muon g-2 experiment for the first time, kicking off a three-year effort to measure what happens to those particles when placed in a precise magnetic field. The answer could rewrite scientists’ picture of the universe and...

NY Allocates $15 Million for Brookhaven Cryo-Electron Microscope

The Brookhaven National Laboratory has announced a $15 million allocation from New York State to fund a cryo-electron microscope at the Long Island Facility for Electron Microscopy, a new facility on its campus. The microscope will operate at 77 K and will provide researchers with a new look at molecular...

Sandwiched Graphene Adopts Andreev States

MIT physicists have found that a flake of graphene, when sandwiched between two superconducting materials, can inherit some of those materials’ superconducting qualities. The electronic state of the graphene changes dramatically here, even at its center, as the particles pair up in Andreev states—a fundamental electronic configuration that allows a...

Auguste and Taylor-Wharton Ink New Distribution Deal

Auguste Cryogenics has signed a long-term liquid cylinder distribution agreement with Taylor-Wharton, becoming the exclusive distributor in Europe, Russia and Israel for Taylor-Wharton’s extensive line of gas and liquid withdrawal cylinders.

Researchers Develop Circuit Refrigerator for Quantum Computers

Cooling has proven to be a major concern for engineers developing quantum computers, but now a research team at Finland's Aalto University says it has invented a quantum circuit refrigerator that could reduce errors in quantum computing. Quantum computers differ from the computers that we use in that, instead of...

Ball Aerospace Developing Cryostat for GUSTO

NASA has chosen Ball Aerospace to design and build a cryostat for its Galactic/Extragalactic Ultralong Duration Balloon (ULDB) Spectroscopic Terahertz Observatory mission, or GUSTO. The mission, led by the University of Arizona, will measure emissions from the interstellar medium, helping scientists to determine the life cycle of interstellar gas in...

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...

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...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
