The particle in cell simulation results, within the limits of the complete set of the Maxwell-Vlasov equations, of the short high-current compensated tubular ion bunches transportation and acceleration in the peaked fence magnetic field are presented. The ion bunch current, at injection in the cusp, is compensated by electrons. It is shown that additional compensation of the accelerated ion bunch space charge by thermal electrons leads to reduction of its energy dispersion and divergence on an exit from the cusp. It is shown also that overcompensation of the ion bunch space charge by thermal electrons leads not only to increase of energy spread and divergence of an ion bunch on an exit from the cusp, but also to deceleration of an ion bunch.
