    IC-100 heavy ion cyclic implanter was designed at the FLNR JINR in 1985 for acceleration of ions from carbon(12C+2) to argon (40Ar+7) with fixed energy of 1.2 MeV/nucl at HF system forth harmonic and of 0.6 MeV/nucl at HF sixth harmonic.
    Special-purpose beam transportation line with polymer film irradiation unit has been created as well as a box for heavy ion beam research. Two-plane beam scan system was installed in the extracted beam transportation line [7] so that to implant ions uniformly over a 600x200 mm target.

    PIG ion source was used at the accelerator to determine the accelerated ion mass range. Years 2003-2005 update resulted in IC-100 being equipped with external axial beam injection system and superconducting ECR ion source which allowed to produce intensive beams of highly charged ions of xenon, iodine, krypton, argon and other heavy elements of the Periodic Table. Helix inflector is installed in the center of the accelerator.

    IC-100 cyclotron was designed to accelerate multicharged ions with A/Z = 5.3 ÷ 6.0, which imposes rigorous criterions on production of intensive beams of highly charged ions of heavy elements. For this purpose the FLNR in cooperation with the LHE research scientists developed superconductive ECR ion source of about 3 T axial field level and 18 GHz SHF heating frequency [3,4]. After the injected beam separation and collimation on a diaphragm 20 mm in diameter 86Kr+15 ion beam current amounts to 60-70 microampere and 132Xe+23 ion beam current comes to 35 microampere.
