Perfect Crystal Diffractometer for Ultra Small-Angle Neutron Scattering
A perfect crystal diffractometer (PCD) for ultra-high resolution small-angle neutron scattering (USANS) measurements is now in operation at the thermal neutron beam port, BT-5. The PCD increases the maximum size of features accessible with the NCNR's 30-m long, pinhole collimation SANS instruments by nearly two orders of magnitude, from ~102 nm to 104 nm.
