Sumitomo Cryogenics of America Acquires Ferran Technology

Sumitomo (SHI) Cryogenics of America, Inc. (SCAI) (CSA CSM), has announced its acquisition of Ferran Technology Inc., a leading-edge provider of vacuum measurement and control instrumentation to the micro-electronics manufacturing industries, as well as scientific research and industrial vacuum markets.

Electro-optical Switch Transmits Data at Record-Low Temperatures

A silicon optical switch developed at Sandia National Laboratories is the first to transmit up to 10 gigabits per second of data at temperatures just a few degrees above absolute zero. The device, according to researchers there, could enable data transmission for next-generation superconducting computers that store and process data...

MRI Scans Help Spot HIV in the Brain

Scientists at University College London have developed a way to use MRI scans to help identify when HIV is persisting in the brain despite effective drug treatment. The team looked at data from 146 HIV patients who were investigated for cognitive problems between 2011 and 2015. There was evidence that...

Liquid or Gas, DUNE Researchers Weigh Transport of Detector’s Argon

Nearly a mile below the surface of South Dakota, scientists are preparing the Deep Underground Neutrino Experiment, or DUNE, a physics experiment that will look at minuscule particles called neutrinos. A beam of neutrinos will travel 800 miles through the Earth from Fermi National Accelerator Laboratory (CSA CSM) to the...

Nominations Open for New KEK Director-General

Japan's KEK, High Energy Accelerator Research Organization, has announced a worldwide search for its next Director-General, whose term will begin April 1, 2018, and last for three years.

Winners Announced for 2017 Fritz London Memorial Prize

Duke University has announced recipients of its 2017 Fritz London Memorial Prize, choosing Jeevak Parpia of Cornell University and William P. Halperin and James A. Sauls, both from Northwestern University.

Transfer Lines

Transfer lines may in some real sense be thought of as the cryogenic fluid analogy of current leads. While current leads carry electrical power to where it’s required in a cryogenic system, transfer lines do the same with cryogenic fluids. Transfer lines range in complexity from very simple U-tubes containing...

Zero Boiloff

Zero Boil Off cryostats are those that contain liquid cryogens but are designed to eliminate or vastly reduce the boil off of the liquid. These cryostats combine some of the advantages of Cryogen-Free systems (e.g. ease of use and long operational lifetime) with the advantages associated with a reservoir of liquid...

Cryomodule

Cryomodule is a term that is most commonly used to refer to cryostats that contain superconducting radio frequency (SRF) cavities. Such cavities are used to accelerate charged particle beams and are a major component of modern particle accelerators. Using the term cryomodule to refer to cryostats containing SRF cavities appears...

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...

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?
