Abstract

SPARC in Frascati is a high brightness photo-injector used to explore advanced beammanipulation techniques. Sub-picosecond, high brightness electron bunch trains (the socalled comb beam) can be generated illuminating the cathode of a RF photoinjector with alaser pulse train and via velocity bunching technique. In this paper different aspects ofthe physics of this advanced beam manipulation technique are discussed combining simulationand measurements. Beam dynamics numerical macroparticle simulations have been compared withthe experimental results for model validation; they allow to gain insights on the beamevolution highlighting several aspects which can not be measured. In particular, we focuson the train evolution in the linac sections and in the dogleg line up to the THz stationand on the effective rms length of the single pulses within the train when it becomesshorter than the resolution.
