NIST Center for Neutron Research (NCNR) Expansion and Reliability Improvements (+$2 million)
Neutron beams have become an indispensable research tool in materials science, biotechnology, chemistry, engineering, and physics because of their ability to image materials and structures nondestructively at atomic and molecular scales. As a measurement probe, neutrons have unique advantages over other nanoscale techniques such as X-rays. The unique sensitivity of neutrons to magnetism and hydrogen is harnessed to study materials that push the frontier of modern technological capability, including advanced superconductors, spin-based electronics, protein function, hydrogen fuel cells, and hydrogen storage materials.
Serving more scientists and engineers (over 2,000 annually) than all other U.S. neutron research facilities combined, the NIST Center for Neutron Research (NCNR) is the nation’s leading neutron facility. The NCNR is especially valued for its “cold” (low-energy) neutron source, which greatly increases the utility of the neutron beam, particularly in biotech and materials research.
Although the NCNR is widely regarded as the most cost-effective and efficiently managed neutron facility in the United States, presently this critical research tool cannot possibly meet the demands placed on it.
Proposed NIST Program
This is a planned increase in funding for the NCNR Expansion Initiative, begun in 2007. When completed, this five-year project will provide:
The FY 2009 funding request supports the next phase of the NCNR expansion to initiate installation, testing, and commissioning of the new neutron instruments (such as spectrometers). These instruments will bring new neutron measurement capability to U.S. researchers by either exceeding the capabilities of current instruments by more than a factor of a hundred, or by providing capabilities that are not currently available in the United States.
In FY 2009, the project will focus on:
Completion of the NCNR expansion will allow:
