Evolutions of the e-beam in the PIC simulation.

(a) Snapshot of the two-dimensional electron density distribution and evolution of the electron phase space (z, E) when penetrating the foil; (b) Corresponding e-beam spectra at z = 2.522, 2.528, 2.533, 2.538, 2.5444 and 2.555 mm, respectively; (c) Corresponding evolutions of the normalized transverse emittance and the e-beam radius versus the propagation distance z.
