Description
We present a design for the experimental validation of relativistic ponderomotive dynamics on a realistic MeV electron-beam platform. The scheme combines an S-band gun with a co-propagating focused laser pulse to induce longitudinal momentum modulation in relativistic electrons. Using a nonparaxial laser-field model and beam-dynamics simulations, we evaluate the expected post-interaction energy signatures and their observability on a practical beamline. Particular attention is given to the dependence of the modulation on laser focusing, beam parameters, and synchronization errors. The analysis identifies the dominant force contributions governing the final energy distribution. These results provide a practical route for translating previously derived relativistic ponderomotive theory into a testable experiment.
