ASC 2016 Highlights Progress in Superconductivity

Over 1,600 researchers and engineers from 36 countries gathered in Denver September 4-9 for ASC 2016, attending plenaries, poster sessions and meetings under the watchful gaze of the Colorado Convention Center’s Blue Bear. Celebrating its 50th year, the conference covered a wide range of topics, from superconducting electronics detectors and...

2016 ASC Best Student Paper Contest

The Applied Superconductivity Conference's Best Student Paper Contest recognizes outstanding presentations made at ASC by full-time students. The ability to describe one’s research, by succinctly capturing key results and ideas in written form as well as by presenting and defending the work in front of an audience of experts, is...

After 50 Years of ASC and Magnet Conductors, What’s Next?

Past and present superconducting magnet technology suggests that cheap, strong, available-by-the-ton Nb-Ti alloy conductors will always be used unless it’s absolutely necessary to use another superconducting material. In this decade “absolutely necessary” has taken on a clearer definition, thanks to ITER, the upgrade of LHC, 1 GHz NMR magnets, the...

Laser Powered Cryocooling Drops to 91 K

Over the last couple of decades researchers around the world have been working on optical refrigeration, a new solid-state cooling scheme based on light-matter interactions, and a team of researchers from the University of New Mexico (UNM) and ThermoDynamic Films, LLC (TDF) is currently working to harness the physics of...

Testing JWST’s MIRI Cooler Compressor Assembly

The James Webb Space Telescope’s (JWST) Mid InfraRed Instrument (MIRI) cooler subsystem features a closed cycle helium Joule-Thomson (JT) cryocooler pre-cooled by a three-stage pulse tube cryocooler. In this paper, researchers from Northrop Grumman discuss tests conducted on the CCA, a flight model sub-assembly that compresses and precools MIRI's helium...

Cryogenic System to Cool Malaysian Data Center

An international consortium has announced plans to construct a green data center that features liquid submersion cooling at a location in Malaysia's Klang Valley. The project aims to increase the sustainability of data centers by changing the way facilities are cooled, therein reducing energy consumption by up to 50 percent,...

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...

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?
