[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 Laboratory Triple Axis (HB-1A)

· Triple-Axis Spectrometer (HB-1)

· Residual Stress (HB-2B)

· Triple-Axis Spectrometer (HB-3)

· 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 is being enhanced per user requests and is accepting submissions starting January 7, 2008. We will continue to incorporate user comments as we improve our systems. We apologize for any inconveniences users may have experienced as we bring our system on line.

This call will cover the experimental period at HFIR and SNS beginning March 2008 through August 2008; it will be open until 11:59 p.m. ET, Monday, January 28, 2008. All previously submitted proposals will expire and will not be considered for this experimental period. This is a necessary step as we progress toward routine operations.

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. For your convenience, one of your previously submitted proposals can be copied and serve as a basis for modification into a new proposal; please see the website for more details.

All proposals will be reviewed for feasibility, safety, and the potential for high impact science. Users of approved experiments must complete access and training requirements prior to beginning their experiments. Please contact neutronusers@ornl.gov or call Judy Trimble, Neutron Scattering Science 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.
