Upcoming events

  • eBEAM summer school 2022

The eBEAM School on Nano-Optics with Free Electrons will take place from September 11th to 16th 2022 on Porquerolles (France).

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 nanooptics 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.

The school will include the following lectures:

  1. Electron microscopy instrumentation basis (Peter Kruit, Delft University of Technology, the Netherlands)
  2. Electron microscopy and spectroscopy basics (Gerald Kothleitner, Graz University of Technology, Austria)
  3. Electron spectroscopies of optical modes (Andrea Konečná, CEIT, Czech Republic)
  4. Electron spectroscopies of excitations in optical materials (Sean Collins, University of Leeds, UK)
  5. Time and quantum coherence in electron spectroscopy (Hugo Lourenço-Martins, CNRS, France)
  6. Space coherence in electron spectroscopy (Axel Lubk, IFW, Germany)
  7. Advanced EELS: vibrational EELS, q-resolved EELS (Demie Kepaptsoglou, Superstem, UK)
  8. Ultrafast PEEM (Walter Pfeiffer, Bielefeld University, Germany)
