  SIS100 is a unique heavy ion synchrotron designed for the generation of high intensity heavy ion and Proton beams. New features and solutions are implemented to enable operation with low charge state heavy ions and to minimize ionization beam loss driven by collisions with the residual gas. SIS100 aims for new frontier and world wide leading Uranium bam intensities. A huge effort is taken to stabilized the dynamics of the residual gas pressure and to suppress ion induced desorption. Fast ramped superconducting magnets have been developed and are in production with highest precision in engineering and field quality, matching the requirements from beams with high space charge. A powerful equipment with Rf stations for fast acceleration, pre- and final compression, for the generation of barrier buckets and provision of longitudinal feed-back shall allow a flexible handling of the ion bunches for the matching to various user requirements. Results obtained with FOS (first of series) devices, status of realisation and technical challenges resulting from the demanding goals, will be presented.

  Four different types of RF cavities are realized for the heavy-ion synchrotron SIS100 which is built in the scope of the FAIR (Facility for Antiproton and Ion Research) project. The standard acceleration is performed by ferrite cavities. Barrier bucket cavities will allow a pre-compression of the beam by means of moving barriers. Bunch compressor cavities are used to realize a rotation in longitudinal phase space by 90 degrees, thereby reducing the bunch length. Finally, a longitudinal feedback system reduces undesired beam oscillations. In contrast to the ferrite-loaded accelerating cavities, the last-mentioned three cavity types are based on magnetic alloy (MA) material. Depending on the type of the cavity system, the realization is done by - or in close collaboration with - different industrial companies and institutions. In this contribution, the realization status of all these synchrotron RF systems is summarized.
