Figure 7. Snapshots with the wedged target.

Figure 7

(a–c) Experimental measurements obtained by focusing the main laser on the edge of a wedged target at different probe laser delays (Δt). The electron bunch is moving above the upper side of the crystal and normally to it. By measuring its time of flight we determined a mean energy of 15 MeV. The signal amplitude corresponds to 2.1 nC charge and the resulting bunch duration is 1 ps (rms). (d–f) Expected EOS signals assuming such bunch parameters. The lack of uniformity in the experimental signals, if compared with the simulated ones, is due to inhomogeneities in both the ZnTe crystal and probe laser spot.
