Russian Physicists Obtain Data on Particle Self-organization in Ultracold Dusty Plasma

Physicists in Russia recently investigated the behavior of particles in dusty plasma at a temperature below 2 K, an experiment that revealed nanoclusters forming in the plasma and the synthesis of polymer fibers taking place at extremely low temperatures. According to the team, such results can be used to create...

Electron Camera at SLAC Films High-speed Molecular Movie

Researchers using an extremely fast electron camera at the Department of Energy’s SLAC National Accelerator Laboratory have made the first high-definition “movie” of ring-shaped molecules breaking open in response to light.

Cryo-EM Reveals Crucial Electrical Switch in Brain

Scientists using cryo-EM have revealed the structure of a critical receptor (AMPA) in the brain associated with learning, memory, behavior and mood. The research was also the first to reveal the structure of AMPA receptors in a natural state, a discovery that could lead to new insight about the mechanism...

Researchers Discover Water that Never Freezes

Can water reach -263°C without turning into ice? The answer is yes, according to a group of physicists and chemists from ETH Zurich and the University of Zurich who identified an unusual way to not only prevent water from forming ice crystals while at extreme sub-zero temperatures but to also...

Working Together as a “virtual telescope,” Observatories Around the World Produce First Direct Images of a Black Hole

MIT News reported on April 10 that an international team of over 200 astronomers had captured the first direct images of a black hole. They accomplished this remarkable feat by coordinating the power of nine major radio observatories on four continents, to work together as a virtual, Earth-sized telescope. In...

Turning Patient Cells into Cancer Fighters

Cancer therapy could soon include a personalized cancer treatment based on engineered immune cells derived from a patient's individual cells. The approach involves attaching proteins to these cells, receptors that target antigens present in cancer cells to then enable a patient’s immune system to seek out and destroy tumors.

Transfer Lines

Transfer lines may in some real sense be thought of as the cryogenic fluid analogy of current leads. While current leads carry electrical power to where it’s required in a cryogenic system, transfer lines do the same with cryogenic fluids. Transfer lines range in complexity from very simple U-tubes containing...

Zero Boiloff

Zero Boil Off cryostats are those that contain liquid cryogens but are designed to eliminate or vastly reduce the boil off of the liquid. These cryostats combine some of the advantages of Cryogen-Free systems (e.g. ease of use and long operational lifetime) with the advantages associated with a reservoir of liquid...

Cryomodule

Cryomodule is a term that is most commonly used to refer to cryostats that contain superconducting radio frequency (SRF) cavities. Such cavities are used to accelerate charged particle beams and are a major component of modern particle accelerators. Using the term cryomodule to refer to cryostats containing SRF cavities appears...

Magnets

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. Particle physics uses accelerators to recreate the conditions of the early universe in an attempt to piece together the complex puzzle of how we got to where we are today. These huge machines are used...

Energy Storage

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. With power lines increasingly congested and prone to instability, strategic injection of brief bursts of real power can play a crucial role in maintaining grid reliability. Small-scale Superconducting Magnetic Energy Storage (SMES) systems, based on...

Astronomy

ASTRONOMY IN SPACE by Peter V. Mason, retired, Jet Propulsion Laboratory, and Visiting Associate, California Institute of Technology. Pmason@alumni.caltech.edu In thinking about the reasons to perform astronomy in space, we first consider the effect of the earth’s atmosphere. On a scale of decreasing energy, gamma rays, cosmic rays, X-rays and...

Cryocoolers

What is a Cryocooler? A mechanism that can extract heat from an object (cooler) and by doing so draw its temperature down below approximately 150 Kelvin (cryo). — (Courtesy Dr. Willy Gully) What is the difference between a Cryocooler and a Cryostat? A cryostat is any device designed to maintain...

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?
