Dynamical ultrafast studies are increasingly becoming relevant for distinguishing nanoscale heterogeneity and probing nanoscale features, whether by full-field imaging or scanning nanoprobes. Relativistic ultrafast electron diffraction (UED) is well-suited for structural dynamics studies, allowing transmission through samples tens to hundreds of nanometers thick, large q-range, and many-electron bunches with femtosecond duration. However, MeV-scale UED probes are typically 10s of microns wide, making application to ultrafast nanoscience challenging. At the High Repetition-rate Electron Scattering (HiRES) instrument at Lawrence Berkeley National Laboratory, we are bringing relativistic ultrafast electron diffraction to the nanoscale to enable a diverse range of nanoscience experiments.
