Two-pulse x-ray photon correlation spectroscopy at Linac coherent light source
Abstract/Contents
- Abstract
- Nearly fully transversely coherent femtosecond x-ray pulses produced by x-ray free electron laser sources opened up the possibilities of direct measurement of atomic scale dynamics of complex systems at their native timescales. One area of particular interest is the investigation of noncrystalline matter such as liquids, glasses, amorphous and disordered systems, and holds the promises of unlocking the mysteries behind the glass transition, liquid-liquid phase transitions, fragile-to-strong transitions, etc. A primary methodology with the potential to extend dynamic light scattering to angstrom and femto- to nanosecond timescale is the so-called two-pulse x-ray photon correlation spectroscopy (XPCS) technique, where the dynamics of the scattering object are imprinted onto the fluctuations of coherent scattering intensity distribution. This dissertation focuses on the instrumentation and methodology of two-pulse XPCS, highlighting the challenges and efforts to establish it as a robust technique at x-ray free electron laser facilities towards measuring ultrafast dynamics in complex matter
