Ultrafast electron diffraction- present status and future advances

Research output: Chapter in Book/Report/Conference proceedingConference contributionAcademic

Abstract

In this review I will first discuss beam requirements for ultrafast electron diffraction, in particular the biggest challenge: what is needed for recording diffraction patterns of complex macromolecular crystals in a single, femtosecond shot. Subsequently I will discuss the present state of the art provided by bright photoemission guns, both non-relativistic DC guns and relativistic RF guns, in combination with RF bunch compression. Finally I will go into several more exotic methods that are being developed to achieve an even higher degree of spatial coherence and temporal resolution: sources based on laser plasma acceleration and ultracold sources based on photoionization of laser-cooled gases or on cryo-cooled semiconductors photocathodes.
