“…In a plasma-based accelerator with multi-GeV energy gain, the plasma will be meters long with a density in the 10 16 cm ÿ3 range [6], and the beams will significantly evolve in their transverse dimensions. Such an evolution is well documented for the case of e ÿ bunches [9,10,14,15]. Numerical simulations indicate that the focusing force a plasma exerts on an e bunch is inherently nonlinear along both the bunch radius and the length [13,16].…”

“…6 are reconstructed from the double-Gaussian approximations applied to the sliced energy distributions. Estimating the magnitude of focusing and defocusing for each energy slice, we can account for the known dynamic modulation of the electron emittance over the bunch length [12], and the variation in the density of the plasma electrons along the bunch [3] unrelated to the focusing induced by the wake's accelerating field. We eliminate this trend in the input beam's divergence by calculating a floating initial divergence F D =2 for each energy slice.…”

“…In Experiment E157 at SLAC, a change in plasma focusing was observed along the bunch, using an exter-nally imposed energy chirp [3,4]. Yet, although this finding was fundamentally important, the phasing between the accelerating and focusing components in the wake field lacked empirical verification.…”
