Alstom Unveils Hydrogen Powered Train

Alstom, a leader in integrated railway systems, unveiled a hydrogen-powered passenger train during an event at InnoTrans, a railway industry trade fair. The new train, Coradia iLint, is modeled after Alstom's diesel operated Coradia Lint 54, but will feature a CO2 emission-free hydrogen fuel cell engine. The first delivery is...

AMSC and Nexans Expand Relationship

AMSC, an energy solutions provider serving the wind and power grid industry, and Nexans Deutschland GmbH (CSA CSM), an expert in the cable industry, have announced a partnership to market and sell AMSC’s Resilient Electric Grid (REG) system and other high performance superconductor power cables in the US and Canada.

Open Access Initiative SCOAP3 Extended Through 2019

CERN has announced the continuation of the global SCOAP3 open access initiative for at least three more years. SCOAP3, the Sponsoring Consortium for Open Access Publishing in Particle Physics, is an innovative partnership of over 3,000 libraries, funding agencies and research organizations from 44 countries. It has made tens of...

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...

Cold Compressors

A common way to provide cooling below the normal boiling point of helium (4.2K) is to reduce the pressure above the bath of liquid helium, thus also reducing the bath’s equilibrium saturation temperature. For example, to produce a 1.8K bath of liquid helium, the saturation pressure has to be reduced...

Kapitza Conductance

Kapitza conductance refers to the heat transfer between a solid surface and a fluid that covers that surface. Fundamentally, it describes the inherent difficulty in transferring energy from a solid to the fluid covering the solid surface. This phenomenon was first observed by P. L. Kapitza in 1941 while studying...

Thermosyphons

A thermosyphon (or thermosiphon) is a device that transfers heat via natural convection in a fluid. The natural convection is driven by gravity with the colder, denser fluid flowing downhill and the warmer, less dense fluid flowing back up. Thus, thermosyphons connect an object to be cooled with a reservoir...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

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?
