Program | Bright, ultrashort X-ray pulses are available from synchrotron and free electron laser sources. Pulses of even shorter duration but low intensity are available via high harmonic generation. Applications of modern X-ray sources in multiple areas of science are growing and current possibilities seem to be limited only by researcher’s imagination. In this tutorial lecture series I will cover basics of X-ray spectroscopy and X-ray imaging. X-ray spectroscopy is the main technique for analysis of electronic structures in molecules, proteins, catalysts and materials. Time resolved X-ray spectroscopy allows to uncover evolution of electronic configurations in time following the excitation. Imaging examples will include high sensitivity X-ray fluorescent imaging for studies of brain and FEL based serial crystallography. For structural techniques extended X-ray absorption fine structure (EXAFS) will be covered as a key techniques for structure analysis in solutions and disordered materials. |
