High-temperature superconductivity starts with nanoscale electronic oases
High-temperature superconductivity doesn't happen all it once. It starts in isolated nanoscale patches that gradually expand until they take over.

Leading physicist becomes executive director of NINT
An expert in nano-electronics will lead Canada’s National Institute for Nanotechnology (NINT) into its second decade. The NINT governing council has named Dr. Marie D’Iorio as its new Executive Director.
NIST physicists benchmark quantum simulator with hundreds of qubits
Physicists at the National Institute of Standards and Technology (NIST) have built a quantum simulator that can engineer interactions among hundreds of quantum bits (qubits)—10 times more than previous devices.
CMS discovers new particle
The Compact Muon Solenoid (CMS) experiment at CERN has submitted a paper for publication describing the first observation of a new particle, an excited beauty baryon called the ?b*0 (?b is pronounced "Csai - bee").
Test facility at KEK becomes an accelerator
On April 13 at KEK’s superconducting radio frequency test facility (STF), researchers successfully transported beam to the beam dump. The dump, located in the last part of the accelerator, is designed to absorb the energy of particles within accelerated beam. Now STF is no longer a test facility: it is...
New Light Source construction more than 70 percent complete
Construction of the $912-million National Synchrotron Light Source II (NSLS-II) at the U.S. Department of Energy’s Brookhaven National Laboratory is more than 70 percent complete – on schedule and on budget.

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...
Primary Standards
Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...
Shrink Fitting
Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...
Telecommunications
From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...
Wind Tunnels
Dr. Robert Kilgore The development of the cryogenic wind tunnel is one of many significant breakthroughs in both cryogenics and wind-tunnel technology made during the past millennium. Interest in the development of high-speed commercial and military aircraft resulted in a review of problems of flow simulation in transonic wind tunnels...
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?
