We performed computational studies on electron beam ablation of space debris. The electron beam trajectories in the ionospheric plasma were calculated using Monte Carlo simulations of electron scattering. Regarding electron beam ablation, the evaporation of aluminum, the main component of debris, due to heating was calculated using molecular dynamics. The increase in electron beam intensity with decreasing neutral oxygen density in the ionospheric plasma and the resulting increase in the number of evaporated atoms from the debris were reproduced.
