Proposals for use of the NIST High Resolution Neutron Powder Diffractometer,
BT-1, may now be submitted via the World Wide Web. Proposals will be reviewed
approximately every two months, which can allow time to be allocated as soon as
two weeks after the proposal has been received. Approximately 25% of the
operating time for this instrument is available to external users through the
proposal system.

The NIST neutron powder diffractometer has 32 detectors and offers excellent
resolution (FWHM 0.2 to 0.3 degrees) over nearly the entire diffraction range
(20-150 degrees, wavelength=1.54A), depending on the desired instrument
configuration. With samples having a volume of 5-10 cc, data can be collected
in 3 hours or less, though samples with masses well below 0.5 g have also been
used successfully with significantly longer data collection times. The sample
temperature can be controlled over the temperature range from 0.3 K to 1100 K
while data are collected.
