FIG. 1.

Typical example of the effect of the plasma wave on a bunch with a length greater than the plasma wavelength. The initial Gaussian bunch (a) is transformed into a train of sub-bunches (b) corresponding to similar phases in the plasma wave while retaining the overall Gaussian profile.

FIG. 2.

Effect of the plasma length and density on the final energy (a), energy spread (b), total charge (c), and emittance (d) of the train of bunches. The solid line represents the dephasing length [Eq. (7)]. The laser and injected electron parameters are described in Table I.

FIG. 3.

Effect of the plasma density and injection energy of the electrons on the final energy (a), energy spread (b), total charge (c), and emittance (d) of the train of bunches. The fixed laser and injected electron parameters are described in Table I and the plasma length is equal to the dephasing length [Eq. (7)]. The dotted line denotes the approximate trapping limit of .

FIG. 4.

Effect of the plasma density and laser power on the final energy (a), energy spread (b), total charge (c), and emittance (d) of the train of bunches. The fixed laser and injected electron parameters are described in Table I and the plasma length is equal to the dephasing length [Eq. (7)]. The dotted line denotes the approximate trapping limit of .
