CSA 2016 Elections Certified

CSA's Board of Technical Directors, at a meeting held during the Applied Superconductivity Conference in Denver, certified results from the society's recent election. Society members chose Peter Shirron, from NASA's Goddard Space Flight Center, as the new President-Elect, and Scott Courts, Richard Dausman, Peter Knudsen and Mark Zagarola as Directors.

Hybrid Magnet to Reach 43 Tesla

Intense magnetic fields are a powerful research tool, and researchers expect the opportunities opened up by the hybrid magnet being built at the CNRS National Laboratory for Intense Magnetic Fields in Grenoble to be vast. Current magnets at the facility operate at 36 teslas, but a new hybrid magnet there,...

BC Technical and Sumitomo Ink Deal

BC Technical, a leading non-OEM provider of medical imaging solutions, has announced a strategic relationship with Sumitomo (SHI) Cryogenics Group (CSA CSM) anticipated to help its customers increase MRI coldhead longevity and reduce cryogen use. The partnership, BC Technical says, means its customers can not only expect the same standard...

Maglab Launching New Zine for Scientists, Nerds and Other Clever People

The National High Magnetic Field Laboratory (CSA CSM) is getting back in the publishing business with a new science magazine set to launch in 2017. Tentatively titled Mag/zine, the publication will focus on high magnetic field research, targeting both scientists and science-interested readers. It is set to publish three or...

Wanted: Undergraduate Women Interested in Physics

The American Physical Society is currently accepting applications for its Conferences for Undergraduate Women in Physics, held concurrently Jan. 13-15, 2017, at universities across the US and Canada. The conferences feature workshops that encourage women to remain in STEM fields by discussing physics careers beyond academia and exposing physics majors...

KEK Opens Its Doors, Guests Tour Facility

Japan's KEK opened its doors in early September and nearly 4,000 visitors braved the late summer heat for a tour of the high energy accelerator research facility. Organizers used the event to showcase the planned International Linear Collider (ILC) project. Visitors were taken behind the scenes at two ILC test...

Refrigerators and Liquefiers

Two of the most common terms used in cryogenics are “refrigerator” and “liquefier.” These terms describe similar and, as will be seen, in some cases identical components. A refrigerator provides cooling (that is, absorbs heat) at cryogenic temperatures. Refrigerators typically put a working fluid (such as helium) through one of...

Air Separation

Air separation is one of the largest, as well as earliest, industrial applications of cryogenics. In this process, cryogenic temperatures are used to separate air into its constituent gases: nitrogen (78.08%), oxygen (20.95%), argon (0.93%) and carbon dioxide (0.3%). Trace gases such as krypton, neon, xenon and helium total far...

Coefficient of Performance and Figure of Merit

The coefficient of performance (COP) is used to describe the effectiveness of refrigerators, including those operating at cryogenic temperatures. The COP is defined as the amount of heat removed at the cryogenic operating temperature of the refrigerator divided by the amount of work that must be applied to remove the...

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...
