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.

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...

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...

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...
