Concrete Applications for Accelerator Science

Particle accelerators are a lot more than simply the engines of particle physics research, according to scientists working on the Accelerator Application Development and Demonstration (A2D2) project at Fermi National Accelerator Laboratory (CSA CSM). Electron beams generated by linear accelerators have all kinds of practical uses, the researchers say, such...

UK commits $88 Million to LBNF/DUNE Project

The United States and United Kingdom have entered into the first-ever umbrella science agreement between the two countries, a move that will see the UK contribute $88 million to the LBNF/DUNE project hosted at Fermi National Accelerator Laboratory (Fermilab, CSA CSM). The funding makes the UK the largest country investing...

IBM Reports Breakthrough in Quantum Computing

Simulating molecules on quantum computers just got easier according to new results obtained with IBM’s superconducting quantum hardware. In an article published in Nature, IBM researchers discuss the implementation of a new quantum algorithm capable of efficiently computing the lowest energy state of small molecules. By mapping the electronic structure...

Northrop Grumman to Acquire Orbital ATK for $9 Billion

Northrop Grumman Corporation has announced its plan to acquire Orbital ATK, Inc., a global leader in aerospace and defense technologies, for approximately $7.8 billion plus the assumption of $1.4 billion in net debt. The boards of both companies have approved the agreement and the transaction is expected to close in...

CEC/ICMC 2017 Conference Recap

Nestled against the coast of lake Monona in Madison WI, over 700 scientists and engineers from around the world bustled around the meeting rooms of Frank Lloyd Wright’s Monona Terrace from July 9-13, 2017, for the 21st joint Cryogenic Engineering and International Cryogenic Materials Conferences.

Flaw Uncovered in Modern Cryogenic Two-phase Flow Modeling

An investigation into popular thermal/fluid design codes begun as an exercise in curiosity by engineers at NASA Glenn Research Center and the University of Florida has uncovered an interesting flaw in modern cryogenic two-phase flow modeling.

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

Cryogenic Electronics

Randall Kirschman, consulting physicist, Mountain View, California ExtElect@gmail.com Cryogenic electronics—the operation of electronic devices, circuits, and systems at cryogenic temperatures—has been a valuable technology for decades. Cryogenic electronics (also referred to as low-temperature electronics, or cold electronics) can be based on semiconductive devices, on superconductive devices, or on a combination...

Particle Physics: High Energy Physics

Cryogenics and High-Energy Physics 1. From symmetry magazine: http://www.symmetrymagazine.org/cms/?pid=1000627: Cryogenics is the study of how materials behave at temperatures near absolute zero. In high-energy particle accelerators, such frigid temperatures reduce the electrical resistance of wires in superconducting magnets, increasing the magnet strength and allowing faster particle acceleration. The same holds...

HTS Degaussing Systems

From the Spring 2009 issue of Cold Facts (Volume 25, Number 2): Thanks to a joint project by the US Navy and a number of industry partners, high temperature superconducting (HTS) technology is now at the heart of an advanced degaussing system aboard the USS Higgins at the naval station...

Magnetic Resonance Imaging

From http://www.superconductors.org: An area where superconductors can perform a life-saving function is in the field of biomagnetism. Doctors need a non-invasive means of determining what’s going on inside the human body. By impinging a strong superconductor-derived magnetic field into the body, hydrogen atoms that exist in the body’s water and...

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...
