Interested researchers are invited to apply for time on the neutron beam instruments at the High Flux Isotope Reactor at the Oak Ridge National Laboratory (http://www.ornl.gov/). Proposals are accepted at any time and are reviewed year-round. Approved experiments are usually scheduled within 90 days. Beam time is available at no cost for non-proprietary use.

Application procedures and detailed facility descriptions are found on our Web site http://neutrons.ornl.gov.
If possible, please submit your proposals by e-mail. Various formats of our proposal form can be retrieved from our Web site.

Available instruments are triple-axis spectrometers, high-resolution powder diffractometer, four-circle single-crystal diffractometer, SANS, reflectometer, double-crystal USANS, a flat-cone geometry PSD diffractometer ( WAND)*, residual stress diffractometer**.

The 30 m SANS will be "shortened" in the next 1-2 months to make space for the cold guide hall, but it should be available again in the Fall. We will not have the full 30/35m distance (for high resolution studies) until the cold source installation is completed. However, we should be able to do "medium resolution" experiments (up to around 100-150 A) in the near future.

Sample environments include: Temperatures = 1.5K to 1900K, Pressures up to 3 GPa, Magnetic fields up to 7 T, and liquid shear cells.

*The WAND has been recently upgraded with a new, state-of-the-art, multi-wire, gas-filled, detector.

**Proposals for the residual stress diffractometer are handled by the High Temperature Materials Laboratory of the Metals & Ceramics Division; see http://htm29.ms.ornl.gov/rsuc/index.html.
