	A ROtating System for Emittance measurements ROSE, to measure the full 4 dimensional transverse beam matrix of an ion beam has been developed and commissioned. Different ion beams behind the HLI at GSI have been used in two commissioning beam times. All technical aspects of ROSE have been tested, ROSE has been benchmarked against existing emittance scanners for horizontal and vertical projections, and the method, hard-, and software to measure the 4D beam matrix has been upgraded, refined, and successfully commissioned. The inter plane correlations of the HLI beam have been measured, yet as no significant initial correlations were found to be present, controlled coupling of the beam by using a skew triplet has been applied and confirmed with ROSE. The next step is to use ROSE to measure and remove the known inter plane correlations of a uranium beam before SIS18 injection.

In order to meet the requirements on beam parameters for the upcoming FAIR facility at GSI, the injector linac UNILAC will be upgraded. The activities comprise development of the sources for stable provision of intense uranium beams at a repetition rate of 2.7 Hz, a revision of the beam dynamics layout of the 120 keV/u RFQ, the replacement of the matching section to the 1.4 MeV/u pre-stripper DTL, and enhancement of the gaseous stripping section efficiency. This section shall also include a round-to-flat emittance adaptor to prepare the beam for injection into the synchrotron SIS18 which has a flat transverse injection acceptance. Finally, the upgrade includes the complete replacement of the 40 year old 11.4 MeV/u Alvarez-type post-stripper DTL with a new DTL, preferably using Alvarez-type cavities with improved beam focusing features, as well as its rf-power alimentations.
