Parameters of the beam Ar¹⁰⁺ at input of the first Alvarez tank for providing maximal transmission and brilliance, minimum emittance growth in all Alvarez for the different currents of beam and distribution of particles were optimized. The task solution had two stages. The first stage is beam dynamics calculation in Alvarez DTL for phase advance 53° in the first Alvarez tank with 11 mA beam current and gauss distribution for finding the best Twiss-parameters to the first Alvarez tank. The optimization was made with accounting longitudinal emittance and separatrix of channel. The second stage is beam dynamics calculation with optimal parameters of matching line to Alvarez DTL for measured input particle distribution. The results of beam dynamics simulation for Ar¹⁰⁺ with 10 mA at input energy 1.4 MeV/u using PARMI-GSI and PARMT-GSI codes are presented.
