Spallation Neutron Source gets initial go-ahead on second target
January 20, 2009The U.S. Department of Energy has given its initial approval to begin plans for a second target station for the Spallation Neutron Source, expanding what is already the world's most powerful pulsed neutron scattering facility located at DOE's Oak Ridge National Laboratory.
The Critical Decision Zero (CD-0) status is the first step in an approximately $1 billion construction project. The Second Target Station (STS) will be optimized for nanoscale and biological sciences with an emphasis on novel materials for energy production, storage and use.
"The approval of CD-0 and the mission need statement for the STS reflects the Department's commitment to securing and expanding this Nation's leadership position in neutron science," said Harriet Kung, DOE Associate Director of Science for Basic Energy Sciences.
With the addition of up to 24 instruments, the number of researchers that will have access to the SNS's unique neutron scattering capability will eventually double from 2,000 to 4,000 annually.
"CD-0 approval is great news for materials research. The second target station will expand the Spallation Neutron Source's capability for studying structure and dynamics on the nanoscale and provide for a growing community of users, maximizing the scientific investment in the SNS accelerator complex," said ORNL Director Thom Mason, who previously led the SNS project through most of its construction and startup phases.
The new target station-- the most intense source of its kind in the world--will generate long pulses of "cold" neutrons, which are cryogenically chilled to wavelengths that are more useful for molecular-scale analysis.
"The added suite of instruments will provide new research opportunities in technologically significant areas. With the SNS's new capabilities for studying materials and processes at the micro- and nanoscale, researchers will have the tools to develop new materials for a broad range of applications including advanced automotive battery technology, new steel alloys and pharmaceuticals," said Ian Anderson, ORNL Associate Laboratory Director for Neutron Sciences.
Research at the first target station at SNS, which has 10 instruments either operating or in commissioning, has already provided new insight into the behavior of materials used for the efficient transmission of electricity, and has facilitated the development of new methods of administering medicines.
As home of the SNS and the recently upgraded High Flux Isotope Reactor, ORNL is the world's leading center for neutron science.
CD-0 is the first of five "critical decisions" that govern construction of DOE facilities and projects, and is required before the development of a conceptual design study and submission of a budget request for the start of project engineering and design efforts. The project completion is estimated for 2020.
ORNL is managed by UT-Battelle for the Department of Energy. Funding for the STS is through the Department's Office of Science (Office of Basic Energy Sciences).

Astrophysics, Symmetries, and Applied Physics at Spallation Neutron Sources by Paul E. Koehler (Editor), Christopher C. Gould (Editor), Robert C. Haight (Editor), Timothy E. Valentine (Editor) The spallation neutron source (SNS) being built at the Oak Ridge National Laboratory (ORNL) will be by far the highest flux pulsed source of epithermal neutrons in the world when it comes on line in 2006. Although the main thrust of the science programme at the SNS will be materials science, the facility could provide outstanding opportunities for research in nuclear astrophysics, fundamental symmetries, and applied nuclear physics. To review the current status of these fields and to begin to assemble the scientific case and the community of researchers for future experiments at the SNS, a workshop on "Astrophysics, Symmetries, and Applied Physics" was held in March 2002 at the ORNL. Over 60 scientists, representing 11 US and four foreign universities as well as many national laboratories... |
