Foundations of Cryocoolers Virtual Webinars

Plan now to join us for this in-depth exploration of all things cryocoolers! Normally presented in conjunction with the International Cryocooler Conference, the educational and experience-based Foundations of Cryocoolers Short Course is moving online with ICC. Perfect for cryogenic veterans and students alike, this online course will provide an invaluable...

ICCRT Postponed to 2021

Following restrictions imposed by Romanian Government to limit Covid19 outbreaks, including guidelines for organized indoor events, organizers of the International Conference on Cryocooler and Refrigeration Technologies were unfortunately constrained and made the decision to postpone the conference originally planned for October 7-10, 2020, in Bucharest to next year—the exact date...

Super-Kamiokande Gets an Upgrade to Detect Neutrinos from Ancient Supernovae

Buried 1-kilometer underground near the city of Hida, Japan, is a 40-meter tall cylinder filled with 50 million liters of water—the Super-Kamiokande neutrino observatory. Since 1996, it has been observing neutrinos—subatomic particles—from solar, extrasolar, terrestrial and artificial sources with highly sensitive optical sensors which record minute flashes of light that...

ASC to Hold All-virtual Conference October 24-November 7

The 2020 Applied Superconductivity Conference (ASC) will be held virtually over two weeks beginning October 24 and will offer a combined virtual platform for plenary, oral and poster presentations, a conference exhibition, a new program for young professionals called ELEVATE, virtual breakouts, coffee breaks and other features.

A Quantum Thermometer to Measure the Coldest Temperatures in the Universe

On August 20, Trinity College Dublin announced that physicists from the college have proposed a thermometer based on quantum entanglement that can accurately measure temperatures a billion times colder than those in outer space. These ultracold temperatures arise in clouds of atoms, known as Fermi gases, which are created by...

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...

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...
