All uranium charge states coming from the new ion source will be injected into GSI heavy ion high current HSI-RFQ, but only design ions U⁴⁺ will be accelerated to the final RFQ energy. A detailed knowledge about injected beam- current and -emittance for pure design U⁴⁺ ions is necessary for a proper beam line design commissioning and operation, while the measurements are possible only for a full beam including all charge states. Detailed measurements of beam current and emittance are performed behind the first quadrupole triplet at the beam line. A dedicated algorithm, based on combination of measurements and results of an advanced beam dynamics simulations, provides for an extraction of beam- current and -emittance for only U⁴⁺ component of a beam. The obtained results and final beam dynamics design for the new straight beam line are presented.
