SCIENCE AND APPLICATIONS OF COHERENT ELECTRON BEAM MANIPULATION

This conference, jointly organised by the Q-SORT, 3D MAGiC, SMART-electron, Holo Workshop, MINEON projects, explores coherent electron-beam manipulation from different, complementary perspectives.

Concepts such as electron coherence, electron phase control & holography, characterisation of magnetic phase, light-electron interaction, phase plates for imaging or for beam shaping, are all at the forefront of electron microscopy research. Moreover, they are also of interest outside the microscopy field.

In this joint conference, we will explore some of these themes together: cross-fertilisation and topic contiguity will stimulate discussions and new ideas. The conference also aims to facilitate networking, fostering an even larger community. The different reference communities of the four organising projects will have the chance to speak to each other.

The themes at the centre of this conference affect the design of electron-based measurement instruments such as the electron microscope and in general of all electron optics. Not only can we measure the electron phase and through it the electric and magnetic fields, but we can also control it, tune the phase of light waves interacting with the electron beam, as well as the kind of electron interaction with the sample — all of this while controlling the state (e.g. the magnetisation) of the sample itself.

The events are all happening online, but preference is given to round tables and discussions, so as to keep things lively and engaging.

The conference is structured around three sessions, pertaining to Q-SORT & SMART-electron, 3D MAGiC, and Holo respectively.

The Q-SORT + SMART-electron session will regard topics such as electron beam shaping, its applications in spectroscopies, electron light interaction, and time-resolved phase-coherent experiments.

The 3D MAGiC session will focus more on the new ideas of control and measurement of surprising magnetic states with unconventional and advanced magnetic field control.

The Holo session will regard the more general field of holography, with emphasis on new ideas for measuring fields, measuring coherence, reconstructing the electron phase, improving the SNR through phase shifting or stack acquisition, and their applications in material science.
