Results of the 2.5-dimensional numerical simulation of the hollow high-current ion beam (HHCIB) dynamics in two presented. The previous study has shown that the good charge and current compensations of the ion beam by the specially injected in accelerating gap electron beam and the thermal electron injection into drift gap of the induction linac occur. With the aim of increasing the ion beam acceleration rate in the two cusps linac the authors have studied the optimal correlation between an accelerating electric field and an electron beam energy. It is shown also that the proposed method of the ion beam compensation ensures the beam stability relative to both electromagnetic filamentation instability and transit-time instability.
