3D charge-density reconstruction in ASTRA with space-charge forces included in simulations for the subfemtosecond rms bunch. The distribution tracked to the screen with the TDS off (a) is shown alongside the distribution of the simulated reconstruction (b), where the transverse information pertains to the screen postion and the longitudinal information to the TDS centre. The longitudinal distribution is sliced according to the longitudinal resolution of 1.1 fs for the reconstruction.
