Merging techniques to create new functionalities with new applications.

The eBEAM project creates a new platform for EM technology with unprecedented capabilities by combining:

  • PINEM to create precise control over the electron wavepacket in space and time
  • Angle-resolved CL to sensitively detect the spectrum, polarization, phase and statistics of light
  • EELS/EEGS to detect energy spectra with resolution below 1 meV
  • Time-resolved EM to probe spatiotemporal dynamics on the nanoscale
  • Event-based detection to detect single electron and photon events with accurate time stamping
  • Electron phase plates to tailor the lateral geometry of electron wave fronts to probe symmetries
  • Correlation and coincidence detection of electrons and light

The EBEAM team’s breakthroughs in electron microscopy that initiated the EBEAM project.

(a) Pulsed-laser controlled shaping of attosecond electron wavepackets (Göttingen).

(b) meV atomic-scale phonon spectroscopy in hBN (Paris/ICFO).

(c) Cathodoluminescence holography revealing nanoscale phase of light (AMOLF).

(d) Programmable phase plate controlling electron wavefronts (Antwerpen).

(e) Electron-light interaction probing nonlinear optical properties (ICFO/Göttingen).

(f) Femtosecond single-electron pump-probe scheme (Kiel).

(g) Resonant cavity module for RF electron beam modulation (ThermoFisher/TUE).

(h) g(2) measurement unit (LAB Cube) (Delmic/AMOLF).

The innovations of the EBEAM project will convert the EM into a new class of investigative equipment. This will create enormous potential for the development of new materials and device technologies. This, in turn, will pave the way to many new applications of materials that will enable the energy transition, novel insights in life sciences to improve our health, and ultra-low power opto-electronics and quantum devices for the digital information society of tomorrow. Making progress in all these areas is essential for Europe to keep its competitiveness in technologies that advance our quality of life.
