Synchrotrons and X-ray Free-Electron Lasers: Techniques and Applications

This lecture covers the techniques and applications of synchrotrons and X-ray free-electron lasers, focusing on lensless imaging and coherent X-ray diffractive imaging. It explains the setup, procedure, and convolution in lensless imaging, as well as the phase retrieval algorithms used in Bragg CXDI. The lecture also discusses the phase problem, resolution, and improvements in resolution down to 10 nm. Applications of Bragg CXDI include obtaining high-resolution 3-D images of strain within nanocrystals and studying the impact of interfaces. The session concludes with a summary of the key points discussed.
