[Neutron] HFIR and SNS Call for Proposals

Oak Ridge National Laboratory is pleased to announce a Call for Proposals for experiments at both the High Flux Isotope Reactor (HFIR) and the Spallation Neutron Source (SNS). This call includes the following nine instruments:

HFIR instruments

· Ames Lab Triple Axis (HB 1A)

· Triple-Axis Spectrometers (HB 1 and HB 3)

· Residual Stress (HB 2B)

· SANS (CG 2)

· Bio-SANS (CG 3)

SNS instruments

· Backscattering Spectrometer (BL 2)

· Magnetism Reflectometer (BL 4A)

· Liquids Reflectometer (BL 4B)

The electronic proposal submission system will open June 1, 2007 for this call, which will cover the experimental period at HFIR and SNS beginning November 2007; the call is open until 6am EDT, Monday, July 16, 2007. For details concerning proposal submission and instrument capabilities, please visit our website at http://neutrons.ornl.gov. This website has specific information (along with names of scientific contacts) about each of the above-mentioned instruments.

In addition, there is an opportunity for earlier experiment time at three HFIR instruments. Proposals for the three triple-axis spectrometers will be considered for HFIR cycle 410 (beginning August 2007) if the proposals are received by Monday, June 18, at 6am EDT. Proposals received after this date (until July 16) for these HFIR instruments will be considered for cycles later in Fall 2007.

All proposals will be reviewed for feasibility, safety, and the potential for high impact science. Users of approved experiments must complete certain access and training requirements prior to beginning their experiments. Please contact neutronusers@ornl.gov or call Judy Trimble, Neutron Scattering Science Division User Office, at 865-241-3675 if you have any questions. Both HFIR and SNS are user facilities funded by the U.S. Department of Energy Office of Science.
