  Flat beams are those which feature unequal emittances in the horizontal and vertical phase space. The present paper is on the planning of the experimental proof of principle. Detailed simulations of the experiment, initially based on linear matrix transformations, are performed. The remarkable flexibility of the set-up w.r.t. to decoupling is addressed, as it can provide an one-knob tool to set the horizontal and vertical emittance partitioning. It was found that the decoupling capability of the set-up is remarkably flexible and the impact and discussion of this finding is treated in a dedicated section

  At the GSI UNILAC, a nitrogen gas stripper is routinely used for stripping of heavy ion beams at 1.4 MeV/u. Different approaches to optimize the stripping efficiency as well as different options to increase the ion charge states for delivery to SIS18 are being investigated. The existing gas stripper was operated with methane and hydrogen gas for stripping of high current uranium ion beams. The results as well as the limitations of these tests will be presented and will be compared to standard nitrogen operation of the gas stripper. In addition, newest results using differently prepared carbon stripping foils for the same ion beams will be reported.
