6D phase space cuts of the electron beam after the plasma exit. (a) Energy vs the longitudinal (z) and transverse (x) position. The macroparticles are colored according to their relative weights (b) 3D spatial distribution. (c) Normalized momentum \(u_x=p_x/m_ec\) vs z and x positions and (d) full transverse momenta \(u_x\), \(u_y\) vs z. In (b, c, d) the macroparticles are colored according to their energy.
