Perfect Crystal Diffractometer for Ultra Small-Angle Neutron Scattering

USANS Beam Profile:

Rocking curve measured for the PCD USANS instrument using a 44 mm diameter sample aperture, exhibiting six orders of magnitude in signal-to-noise (S/N). The intensity is in units of counts per second (s^-1) in the detector. The dash-dot curve is the theoretical profile for a pair of triple-bounce crystals.
