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...

Liquid Hydrogen

Hydrogen becomes a liquid at 20K and 1 bar. Liquid hydrogen (LH2) is an important substance in industry, transportation and research. Industrial uses of hydrogen include applications in the electronics, glass, chemical and metal processing fields. In these applications, the hydrogen is generally used as a room temperature gas but...

Superconducting Radiofrequency Cavities

Superconducting radio frequency (SRF) cavities represent an important application of cryogenics and superconductivity. SRF cavities are a technology for accelerating charged particle beams via the transfer of radiofrequency (RF) energy to the beams via resonant structures. As such, they are frequently found in large particle accelerators used for scientific research....

Thermal Radiation Shields

Actively cooled thermal radiation shields are a common feature of cryostats whose lowest temperature is less than 77K. These shields, which typically operate at temperatures between that of LN2 and 40K, block thermal radiation from higher temperatures from reaching lower temperature cryogenic components or fluids. Since the heat radiated from...

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 comparing chest freezers and upright freezers

Currently we use in our Biobank an upright -80 freezer to store all our samples. We are planning to buy a fully automated bio-repository storage that will do the picking of samples under restricted conditions. But in the meantime I foresee that we have to pick the samples manually. The...

Need recommendations for cryogenic vials

I am looking into standardizing our range of bio storage tubes (cryogenic vials). These will be for both blood and tissue samples and their derivatives. Any recommendations, comments on Micronics, Nalgene, Nunc and or others that are suitable for long term -80 C and -196 C storage, DNA/RNA suitable, would...

We need a custom machine for flash freezing of water

We are an ice making company and have started a new project, which is related to flash freezing of water. It is based on cryogenics technology and we need a custom made machine. I would kindly ask you to pass me a few companies who would be interested in such...

Looking for a pump suitable for cold liquids

I would like to construct a small cooling circuit (appr. 50 x 50 cm) pumping liquid at a temperature down to -120°C from a cold reservoir to the specimen to be cooled. The tubes and connections are not a problem, but does somebody know a pump (suction/compression for circulation) suitable...
