eBEAM School on Nano-optics with Free Electrons 2022

Electron optics and spectroscopy instrumentation developments in the last 20 years have considerably widened the range of applicability of electron beam techniques to nano-optics: meV beam energy spread, single atoms imaging capabilities, electron wavefunction shaping, fs pump probe experiments, and efficient light coupling to and from samples are a reality. This has enabled the study of a variety of excitations (plasmons, phonons, excitons...) at extreme spatial, temporal and spectral resolutions. Therefore, new theories have blossomed to explain exciting results coming from electron energy-loss spectroscopy (EELS), cathodoluminescence (CL) and photon induced near-filed electron microscopy (PINEM), and central concepts of nano-optics or quantum optics have been shown to be applicable to electron-based spectroscopies, For this reason, it is high time for a school aiming at spreading knowledge about these new concepts and techniques and at fomenting the interest of a new generation of academics in this blooming field. That is the object of the eBEAM school focused on electron spectroscopies for nano-optics. Courses will cover: the basics of electron instrumentation and spectroscopies; electron-matter-light interaction; electron spectroscopies of optical material; time, space, and quantum coherence in electron spectroscopy; advanced EELS and CL; photoemission;
