In the transport lines the transverse profile determination will be based mainly on intersecting methods: Scintillations screens, SEM-Grids, Multi-Wire-Proportional Chambers and possibly Optical Transition Radiation screens. The devices are tested at the existing SIS18 at GSI where ions are ex-tracted either in a fast mode (about 1 mus) or resonant mode within about typically 0.3 s. The imaging properties of scintillation screens of different materials (ceramics, phosphor screens and single crystals) with ion beams with energies above 300 MeV/u were investigated. Over intensities 10⁵ to 10⁹ particles per pulse the light yield for the screens is linear with respect to the ion intensity. Moreover, the radiation resistance of the screens was tested. The applicability of optical transition radiation for beams of velocities below 90%c was investigated systematically with heavy ions. The experimental results are compared to wire-based methods obtained with SEM-Grids and MWPCs.
