The uniquely high flux of epithermal neutrons available at a spallation neutron source enable extremely short d-spacings, as low as 0.3 Å, to be measured on POLARIS. The very wide Q range thus accessed is invaluable in the refinement of site occupancies and temperature factors in disordered materials, such as solid electrolytes and high Tc superconductors, using powder diffraction data.

- Time-resolved measurements
- Diffraction studies of very small sample volumes
- Samples at high pressures
