The warm section will provide 20 percent of the total acceleration of the Spallation Neutron Source’s linear accelerator.
With the recent "warm commissioning" of its linear accelerator, Oak Ridge National Laboratory’s Spallation Neutron Source (SNS) has passed a crucial test and milestone on its way to completion in 2006.
The SNS’s linear accelerator, or linac, is composed of two sections: the "warm," or room temperature section, and a superconducting section that operates at temperatures hundreds of degrees below zero. Los Alamos National Laboratory, part of the team of six DOE national laboratories collaborating on the SNS construction project, is responsible for the warm linac. "The successful commissioning of the warm linac is another step toward the 2006 completion of the SNS, and again demonstrates the success of the collaboration of national labs in keeping the project on time, on budget and on scope," said SNS Director Thom Mason.
The warm section will provide 20 percent of the total acceleration of the 1,000-foot-long linac. The linac’s superconducting section, provided by the Thomas Jefferson National Accelerator Facility, will provide 80 percent of linac acceleration. Testing also has begun of components of the superconducting portion, which consists of niobium cavities chilled by liquid helium to minus 456 degrees Fahrenheit.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
