Numerical analyses for beam dynamics in a compact simulator constructed by an electron beam device are carried out in space-charge-dominated regime for heavy-ion beam driven inertial confinement fusion. In strong space-charge-dominated regime, it is expected that fine structures of the charge distribution of the beam bunch are canceled, and the beam current waveform becomes smooth, because of the repulsion force due to the space charge effect. However, the numerical simulation results indicated that the fine noisy error of the voltage applied at the gap is obstinate in the phase space for this study.
