	Funding: BMBF The FAIR project requires a dedicated proton injector for the creation of high intensity secondary antiproton beams. This machine will be the first high intensity linear accelerator based on CH-DTL. The status of the project, with particular emphasis on the construction of the first RF prototype is presented.

	The FAIR Proton Linac is a 70mA, 70 MeV. 325 MHz linear accelerator based on CH cavities. The focusing scheme is provided by an asynchronous KONUS lattice period. Random misalignment and rotation errors of the quadrupoles, together with phase and RF settings of the power source plays a major role in beam losses. Those effects are investigated and the beam dynamics results, including several source of errors, are presented and discussed.

THPWO010	Charge Stripping Tests of High Current Uranium Ion Beams with Methane and Hydrogen Gas Strippers and Carbon Foils at the GSI UNILAC	3779

	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.
