Quantifying Synchrotron Radiation: Coherence and Applications

This lecture covers the concept of coherence in synchrotron radiation, including transverse and longitudinal coherence, coherent fraction, and the impact of imperfect optics on coherence. It also discusses the types of coherence, such as longitudinal and transverse coherence, and how the coherent fraction increases with reduced emittance. The differences between synchrotron radiation and x-ray free-electron laser coherence are highlighted, along with the importance of perfect optics in practical applications.
