Recovery Act to fund testing and development of SRF cavities

From Fermilab Today, September 4, 2009: In August, the Department of Energy announced that the American Recovery and Reinvestment Act will provide Fermilab with $52.7 million to test and develop superconducting radio frequency cavities, a key technology for next-generation accelerators and the future of particle physics.

Fermilab participates in final Science Chicago Labfest

On Friday, August 21, Fermilab volunteers, docents and Education Office staffers collaborated to make physics fun and accessible at Labfest, a series of outdoor summer science fairs taking place throughout the Chicagoland area.

Recovery Act funds go to test bismuth-based material

The Very High Field Superconducting Magnet Collaboration will soon be using $2 million in Recovery Act funds to test BCCO2212, a bismuth-based material that may allow scientists to create high-field superconducting magnets able to acheive twice the strength of existing magnets.

Chart Energy & Chemicals signs agreement for LNG opportunities

Chart Energy and Chemicals, a wholly-owned subsidiary of Chart Industries, has signed a joint agreement with Toyo Engineering Corporation (TOYO) of Japan to jointly pursue certain mid-scale liquefied natural gas (LNG) opportunities.

Boeing 777 and problems with ice in fuel

In January 2008 British Airways flight BA038, a Boeing 777 that departed from Beijing, crashed while on final approach to London Heathrow airport after both its jet engines lost power, a condition known as roll-back. Dr. Ralph G.Scurlock explains how the UK and US Air Accident Investigation authorities, together with...

FEI’s installs Titan Krios TEM at Tsinghua University

FEI, a provider of 3D molecular, cellular and atomic-scale imaging systems, has announced the completed installation of its Titan Krios™ cryo transmission electron microscope (TEM) at Tsinghua University in Beijing.

Two-Phase Flows

Two-phase flows are those flows in which there is a mixture of two physical states (solid, liquid or vapor). In cryogenic applications, such flows are almost always a mixture of a cryogenic liquid along with its corresponding vapor. A mixture of liquid helium and helium vapor would be a typical...

Supercritical Fluids

A supercritical fluid is defined as a substance whose temperature and pressure exceed those of its critical point. Every pure substance has a critical point that is defined in thermodynamic space by a critical temperature and a corresponding critical pressure. For example, the critical point for helium has a critical...

Brayton Cycle

The Brayton cycle is one of the many thermodynamic cycles used to generate cooling at cryogenic temperatures. Strictly speaking, when referring to cooling we should call this the reverse Brayton cycle as the original Brayton cycle describes the process of power generation or propulsion via a gas turbine. In many...

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?
