PBO Fibre Diffraction
This image shows an example of scanning single-fibre microdiffraction on beamline ID13. Diffraction patterns were generated across a single fibre (in this case Poly{p-phenylene benzobisoxazole} or PBO) at 2 micron intervals. To demonstrate this, the diffraction patterns generated at each position across the fibre have been superimposed (scaled for beam diameter and position) upon a Field-Emission-Gun Scanning-Electron-Microscopy (FEG-SEM) micrograph of a single PBO fibre.
The diffraction patterns shown above were generated using capillary optics on beamline ID13. The beam was stopped down to a spot size of approximately 3 microns in diameter using a capillary and aperture. An image showing the sample in-situ and primary optical elements is shown below:
