    "abstract": "The dynamics of transient electric fields generated by the interaction of\nhigh intensity laser pulses with underdense plasmas has been studied\nexperimentally with the proton projection imaging technique. The formation of a\ncharged channel, the propagation of its front edge and the late electric field\nevolution have been characterised with high temporal and spatial resolution.\nParticle-in-cell simulations and an electrostatic, ponderomotive model\nreproduce the experimental features and trace them back to the ponderomotive\nexpulsion of electrons and the subsequent ion acceleration.",
