  The wavelengths and energies of thermal and cold neutrons are ideally matched
to the length and energy scales in the materials that underpin technologies of
the present and future: ranging from semiconductors to magnetic devices,
composites to biomaterials and polymers. The Spallation Neutron Source (SNS)
will use an accelerator to produce the most intense beams of neutrons in the
world when it is complete at the end of 2005. The project is being built by a
collaboration of six U.S. Department of Energy laboratories. It will serve a
diverse community of users drawn from academia, industry, and government labs
with interests in condensed matter physics, chemistry, engineering materials,
biology, and beyond.
