With the aim to provide synergistic and complementary experimental capabilities for the study of ultrafast processes at their fundamental length and time scales SLAC National Laboratory, operator of the world's first hard X-ray free electron laser, the Linear Coherent Light Source, has recently started an initiative for ultrafast electron scattering and microscopy. This contribution will discuss the setup for femtosecond time-resolved MeV electron diffraction, which has been brought into operation over the last few months at SLAC's Accelerator Structure Test Area (ASTA), as well as results from first user experiments addressing the ultrafast lattice response in laser-excited thin Bismuth-films.
