New Technique to Probe High Temperature Superconductivity

Researchers at the University of Illinois at Urbana-Champaign, collaborating with scientists at the SLAC National Accelerator Laboratory, have shed new light on how disparate states can exist adjacent to one another. Illinois Physics post-doctoral researcher Matteo Mitrano, Professor Peter Abbamonte and their team applied a new X-ray scattering technique, time-resolved...

Chinese Researchers Improve 3D Printing PCL Scaffolds with Extrusion-Based Cryogenics

Researchers used 3D porous Polycaprolactone (PCL) scaffolds with combined extrusion-based cryogenic 3D printing and freeze-drying in an attempt to overcome existing limitations like affordability, lack of efficiency in fabrication and inferior process control.

Experiments Explore the Mysteries of “Magic” Angle Superconductors

A team led by Princeton physicist Ali Yazdani has shown that strong electron interactions play a key role in the superconductivity that has been discovered in graphene, a material made up of single-layer sheets of carbon atoms.

LHC Magnet Repair Has Begun

Major work is underway on the CERN Large Hadron Collider (LHC) with the extraction of magnets from the accelerator tunnel. During the second long shutdown, 22 of these large magnet components (including 19 dipoles) have to be replaced, especially as several have been showing operating deficiencies.

Resurrected Detector Will Hunt for Some of the Strangest Particles in the Universe

Brought from Italy's Gran Sasso National Laboratory two years ago, ICARUS—an outdated acronym for Imaging Cosmic And Rare Underground Signals—will soon start a second life seeking perhaps the strangest particles physicists have dreamed up, oddballs called sterile neutrinos. Icarus will resume the neutrino hunt at Fermilab. If they exist, sterile...

Aerogel Could Be a Key Building Material for Mars

NASA scientists are exploring how aerogel, a translucent, Styrofoam-like material, could be used as a building material on Mars. Aerogel retains heat; structures built with it could raise temperatures enough to melt water ice on the Martian surface.

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

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?
