Abstract: Relative ionizations(Bragg curves)of 30MeV/u and 25MeV/u 40Ar ion beams supplied by HIRFL through degraders of Mylar films with different thicknesses were measured respectively.The experimental results were compared with calculations by TRIM88 code.It is found that the experimental results are in good agreement with the calculated ones when the 40Ar ions penetrate a smaller distance from target surface.Furthermore,a heavy ion radiotherapy planning for shallow-seated and small tumor is put forward according to the calculated relationship between intermediate energy heavy ion penetration depth in water and relative ionization.
