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.
