OAK RIDGE, Tenn., Jan. 16, 2009 -- The 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,"
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).

God job!. I hope you will post more news about neutron sciences. I'm so interested in that stuff.
In Europe they are working on the design of an spallation neutron source (ESS) like this new SNS (long pulsed, I remember). In fact, the are developing the targets options in collaboration with the SNS. I think this is good for Europe, in order to keep the high investigation level. But they haven't still decided in wich country will build this ESS. They have two options: Lund (in Scandinavia) and Bilbao (in Spain). I hope it'll be the last one (well, I'm from Spain :). I invite you to the No official blog (esns.blogspot.com) and you could decide your choice. Bye!
