Fig. 4.
Electron (top panel) and proton (bottom panel) energy distribution for the generic case presented in Table 1. The colour scale represents five different sections (I1–I5) of the emitter that correspond to intervals of length Δθ = 0.15π, starting in θ ɛ [0, 0.15π) for I1, and so on. The black dashed line is the total particle distribution (i.e. the sum of all curves).
