$Powder Diffraction - Spallation Neutron Source$

$Single Crystal Diffraction - Spallation Neutron Source$

<strong>Diffuse</strong> scattering poised for a revolution! • Synchrotron sources /new tools enable new applications – Intensity for weak signals – High energy for simplified data analysis – Small (dangerous) samples • Advanced neutron instruments emerging – Low Z elements – Magnetic scattering – Different contrast • New theories provide direct link between experiments and first-principles calculations Experiment Theory Major controversies have split leading scientists in once staid community!
What you already know- arrangement of atoms redistributes scattering • Familiar light example • Practical applications- zero background plates for powder diffraction • Wavediffraction X-ray or neutron beam
