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.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
