synchrotron x-ray techniques
**Synchrotron X-Ray Techniques** encompass the **suite of X-ray characterization methods performed at synchrotron radiation facilities** — providing extremely bright, tunable, polarized X-ray beams that enable measurements impossible with laboratory X-ray sources.
**Key Synchrotron Advantages**
- **Brilliance**: 10$^{10}$-10$^{12}$ times brighter than lab sources — fast measurements, weak signals.
- **Tunability**: Continuously tunable energy for resonant measurements (XANES, EXAFS).
- **Coherence**: Partially coherent beams enable ptychography and phase-contrast imaging.
- **Micro/Nano Focus**: Sub-100 nm X-ray beams for nano-XRF, nano-diffraction.
**Key Techniques**
- **XAS (XANES/EXAFS)**: Chemical state and local structure.
- **Nano-XRD**: Strain/phase mapping with ~50 nm resolution.
- **Nano-XRF**: Elemental mapping with ~50 nm resolution.
- **CD-SAXS/GISAXS**: Nanostructure metrology.
**Synchrotron X-Ray Techniques** are **the ultimate X-ray laboratory** — providing every X-ray characterization capability at brilliance levels impossible in the fab.
