INTRODUCTION <strong>2008</strong> ANNUAL REPORT<br />

Welcome<br />
Ian Anderson,<br />
Associate Laboratory Director<br />
for <strong>Neutron</strong> <strong>Sciences</strong><br />
When I look back at the changes that have occurred in the past year, I can’t<br />
help but marvel at the progress we’ve made in increasing and improving the<br />
performance and instrumentation of the <strong>Spallation</strong> <strong>Neutron</strong> Source (SNS)<br />
and High Flux Isotope Reactor (HFIR), bringing users to our facilities, and<br />
producing scientific results. I must thank the staff of the <strong>Neutron</strong> <strong>Sciences</strong><br />
Directorate and our sponsor, the U.S. Department of Energy (DOE) Office<br />
of Basic Energy <strong>Sciences</strong>, for its demonstrated commitment to the vision<br />
of providing the scientific community with unprecedented capabilities for<br />
understanding the structure and properties of materials.<br />
Early in the year, SNS became the official Guinness World Record holder<br />
for the most powerful pulsed spallation neutron source. With every increase<br />
in power during the year, we continued to break that record and<br />
ended the year at more than twice the power that won us the record. In<br />
total, beam power was increased by nearly a factor of four to 625 kilowatts.<br />
The coming years will remain a challenge as we work to achieve<br />
1.4 megawatts of beam power by FY 2010 or CY 2011. At HFIR, the<br />
new cold source operated successfully all year, providing unique capabilities<br />
to the research community. HFIR finished the year completing<br />
six cycles and beginning a seventh, which allowed us to provide<br />
instrument time to students participating in the <strong>Neutron</strong> and X-Ray<br />
Scattering School.<br />
We made significant progress toward providing a full complement<br />
of instruments at SNS and HFIR (25 and 11, respectively)<br />
by completing 4 instruments at SNS (CNCS, SNAP,<br />
SEQUOIA, and FNPB) and 2 at HFIR (Powder and Single-Crystal
