ABSTRACTThe new high-resolution neutron powder diffractometer BT-1 at the NIST reactor has proven to be a powerful and versatile instrument in its first year of operation. With 32 detectors arranged at 5° intervals and a 12° 2θ scan range, powder diffraction patterns can be collected to 167° 2θ. There is a choice of three monochromator take-off angles (75°, 90°, and 120°) so that the peak-width minimum can be matched to the rf-spacing range that is most important for each sample; all choices have a wavelength close to 1.54 Å. Data can be collected on sample sizes ranging from 200 mg to 30 g. Temperatures of 0.3 K to 1400 K are routinely available, and a magnetic field of 7T can be applied with a superconducting magnet. Typical data collection times range from 1-12 hours depending upon sample size and desired resolution. Examples are given of a variety of materials applications.
