Residual Stress Diffractometer

The Residual Stress Diffractometer is used for measuring lattice strains and preferred orientation (texture), for studying residual and applied stress in engineering materials, and the effect of materials processing on preferred orientation. Designed for versatility, the heart of the instrument is a rotating drum that allows - together with three monochromators - to select wavelengths from 0.08 nm to 0.32 nm. This enables the measurement of d-spacings anywhere between 0.06 nm up to 0.22 nm at the optimal 2theta=90 deg..

CHRNS MACS - The Multi Axis Crystal Spectrometer

 The Multi Axis Crystal Spectrometer at the NIST Center for Neutron Research is a third generation cold neutron spectrometer that provides ultra high sensitivity access to dynamic correlations in condensed matter on length scales from 0.1 nm to 50 nm and energy scales from 2.2 meV to 20 meV. The project is funded jointly by the NIST Center for Neutron Research, the National Science Foundation, and the Johns Hopkins University.

10m SANS - Small Angle Neutron Scattering

The 10 meter Small Angle Neutron Scattering (10m SANS) instrument is designed to measure correlations in spatial structure within solid and liquid materials. The technique measures deflections of a neutron beam as it passes through a sample of interest. The spectrum of deflected neutrons reveals important details such as the state of the material (i.e. amorphous, crystalline, semi-crystalline, liquid crystalline, or some combination), how composition is distributed relative to other structures (i.e.
