SLAC launched the Ultrafast Electron Diffraction and Imaging (UED&UEM) initiative with the objective of developing the world leading ultrafast electron scattering instrumentation, complementary to the X-ray Free Electron Laser - Linac Coherent Light Source (LCLS). SLAC has developed a UED setup at the Accelerator Structure Test Area (ASTA), with the goal of providing MeV, 100-femtosecond-scale electron pulses to support an ultrafast science program [1]. The first UED ultrafast science experiment published in Nano Letters, where large amplitude wrinkles of monolayer MoS2 generated by the light pulse' more than 15 percent of the layer's thickness, was observed. This is the first time anyone has visualized these ultrafast atomic motions. Ultrafast MeV electrons also made it possible the direct measurement of phonon occupations as energy is transferred from electrons into the lattice in laser-heated gold (APL). The rotational wavepacket dynamics of laser-aligned nitrogen molecules were captured in gas-phase electron diffraction experiment using MeV electrons. We achieved an unprecedented combination of 100-fs (rms) temporal resolution and sub-Angstrom (0.76 Å) spatial resolution that makes it possible to resolve the position of the nuclei within the molecule(Nature Communications).
