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...

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

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...

Power usage: cryogenic systems vs. regular refrigerators

A recent project highlighted to me that closed cycle cryogenic cooling systems use far more electrical power to reduce temperatures by a few watts than regular refrigerators. I am sure it must be something to do with the extra difficulty of removing the heat from the liquid nitrogen or similar...

Redundancy strategies for mechanical -80C freezers

I was wondering what kind of redundancy strategies are people using for their mechanical -80C freezers? I am aware of the following. Please add if you are doing something different. 1) 1 Backup freezer for every 10 freezers – Empty and maintained at -80C at all times 2) Backup C02...

Method to move components in a cryogenic environment

Does anyone know of a method with which to reliably move components in a cryogenic environment? We are interested in moving detectors in a cryogenically cooled (2K) vacuum chamber, which is contained within a larger cryostat/isolation vacuum with thermal shields. As the desired horizontal or vertical displacement is between 10...
