SANS vs. Synchrotron SAXS<br />
• SAXS & SANS<br />
– nm scale structural analysis (~1nm-1μm)<br />
– Non-destructive<br />
Non destructive<br />
– In-situ<br />
• Synchrotron X-rays<br />
– High throughput<br />
– Time-resolution (ms – ps)<br />
– Tiny beams – micr<strong>of</strong>ocus: e.g. scanning <strong>of</strong> cells<br />
• Neutrons<br />
– ‘see’ light atoms: polymers, biology, s<strong>of</strong>t condensed matter, hydrogen in metals<br />
– Isotope labeling<br />
– High penetration<br />
• bulky specimens, e.g. residual stress in motor block<br />
• complicated environments (P,T), e.g. 4He cryostat<br />
– Magnetic contrast<br />
