Electric Field Generated by Transition Radiation of a Short Bunch
We calculate distribution of electric field in the image plane of the transition radiation focused with a thin lens. A simple formula is derived that gives the maximum value of the electric field in the focus in terms of the electron beam parameters. This formula is useful for a quick estimation of the electric field in terahertz experiments.
