The GSI Universal Linear Accelerator UNILAC and the synchrotron SIS18 will serve as injector for the upcoming FAIR-facility. The UNILAC-High Current Injector will be improved and modernized until FAIR is commissioned and the Alvarez poststripper accelerator is replaced. The reference heavy ion for future FAIR-operation is uranium, with highest intensity requirements. To re-establish uranium beam operation and to improve high current beam operation, different subjects have been explored in dedicated machine investigation campaigns. After a beam line modification in 2017 the RFQ-performance had deteriorated significantly; new rods have been installed and the RF-working point has been redefined. Also the Superlens-performance had become unsatisfactory; improved with a modified RF-coupler. With a pulsed hydrogen gas stripper target the uranium beam stripping efficiency could be increased by 65%. Various work has already been carried out to establish this stripper device in routine operation. With medium heavy ion beams a very high beam brilliance at the end of transfer line to SIS18 was achieved. Results of the measurement campaigns and the UNILAC upgrade activities will be presented. 899 - ohne Topic (POF4-899) G:(DE-HGF)POF4-899 POF4-899 POF IV 0 Dataset connected to DataCite Accelerator Physics Other MC4: Hadron Accelerators Other theory no experiment theory work (theory) EXP:(DE-Ds200)theory-20200803 EXP:(DE-Ds200)no_experiment-20200803 EXP:(DE-Ds200)no_experiment-20200803 0 Barth, Winfried P:(DE-Ds200)OR0062 1 gsi Miski-Oglu, Maksym P:(DE-Ds200)OR7265 2 gsi Scheeler, Uwe P:(DE-Ds200)OR1097 3 gsi Vossberg, Markus P:(DE-Ds200)OR6800 4 gsi Yaramyshev, Stepan P:(DE-Ds200)OR1430 5 gsi Zimmermann, Frank 0000-0001-9787-8917 6 Editor Tanaka, Hitoshi 0000-0003-1848-2338 7 Editor Sudmuang, Porntip 8 Editor Klysubun, Prapong 9 Editor Sunwong, Prapaiwan 10 Editor Chanwattana, Thakonwat 11 Editor Petit-Jean-Genaz, Christine 12 Editor Schaa, Volker R.
