Description
In this talk, I will discuss how the collective field of a relativistic electron beam can be used to instigate novel quantum dynamics and allow us to study ultrafast physics beyond typical laser-excited systems. At LCLS, the beam-supported fields can be shaped into strong (V/A), broadband (0-10 eV), and/or microbunched pulses that are intrinsically synchronized and mutually coherent with a soft x-ray laser. Preliminary experience commissioning a photon-electron pump-probe experiment (PEPPEx) illustrates the opportunities and challenges associated with using a space-charge field for ultrafast science.
