    "abstract": "The GSI Unilac was upgraded as a high current injector for the SIS in 1999.\nTherefore, the stripping section [1] at 1.4 MeV/u, where a beam transport under\nhighest space charge conditions and multi beam operation had to be established,\nwas completely new designed. Results of the commissioning of the stripper\nsection will be presented. The beam transport to the new gas stripper, and the\ncharge state analysis under space charge conditions confirmed the calculations.\nA 238U4+ beam - coming from a MEVVA ion source and accelerated by the new\ninjector linac- was stripped (with the expected stripping efficiency) to the\ncharge state 28+ and successfully separated by the new spectrometer (15 degree\nand 30 degree kicker magnets). The transport and matching to the poststripper\naccelerator under highest space charge conditions was investigated with a 15\nemA 40Ar10+ beam. Especially space charge and charge state dependent emittance\ngrowth effects in 6d-phase space will be discussed.",
