Notes:
We examine computationally the interaction of a pulse of relativistic electrons that is injected perpendicular to the direction of propagation of a relativistic plasma wave. Such a study is useful for evaluating the feasibility of using transverse beam injection as a diagnostic of the amplitude of electric fields in a plasma wave, as well as for determining the suitability of using such waves as extremely short wavelength undulators for generating radiation from free electrons. We use 2D and 3D models which include the effects of transverse and longitudinal fields of the plasma wave, its finite size and electron beam emittance. We find that the change in the spot size of a short electron bunch as it traverses a relativistic plasma wave can indeed be a sensitive diagnostic of its local amplitude-width product.
