The perspectives of ultrafast electron scattering techniques

Fabrizio Carbone
EPFL - Lausanne (CH)

Abstract
Based on the most recent achievements by means of fs electron diffraction, spectroscopy and microscopy, we will discuss the perspectives that these tools have for different areas of investigation. In particular, we will show the ability of ultrafast electron beamlines to perform fs-resolved diffractive imaging as well as time-resolved holographic studies of 2D systems composed of light elements such as carbon and hydrogen. In the most advanced dynamical transmission electron microscopes (DTEM), direct space imaging with spatial resolution of 1 nm and time resolution in the order of few hundreds of fs can be obtained in addition to a high sensitivity to subtle magnetic entities like skyrmions and superconducting vortexes. Moreover, the DTEM offers a unique playground for studying the interaction between photons, electrons and matter, sheding light on fascinating applications like nano-scaled accelerators and near-field microscopy. The combination of this technology with newly available highly coherent X-rays beams offers unprecedented opportunities for the study of naturally occurring materials and engineered nano structures, the aim of this seminar will be to discuss the potential of such experiments at large-scale facilities
