Attosecond bunching and streaking of sub-relativistic electron beams for ultrafast diffractive imaging

Speaker:  Yuya Morimoto, RIKEN

Program Description:
Motion of electrons in a material occurring on attosecond timescale is closely related to mechanism of chemical reactions and material’s optical properties. In order to directly visualize electronic motions, we are developing electron-beam imaging methods with attosecond resolution. In this talk, I will introduce our recent works on the bunching of sub-relativistic electron beams down to sub-femtosecond durations. Electrons in a beam were bunched by an electric field of a laser pulse, and bunch durations were measured via real-space streaking induced by an electromagnetic field of another laser pulse. I will discuss potential applications of the attosecond electron beams to chemistry and material science.
