At low energy, the beam transport is dominated by the charge space field which in many cases can induce a halo formation, emittance growth and eventually beam losses. Moreover, beam dynamics in LEBT features a unique specificity: space charge compensation induced by ionisation of the residual gas by the propagating beam. In order to attempt to reach a better understanding of space charge compensation and particles dynamics in LEBTs, extensive numerical simulations using the PIC code Warp have been performed. Simulation results for light ions beams propagating in the LEBT of the IFMIF-LIPAc and MYRRHA accelerator will be presented and compared to experimental results.
