TI - UNILAC Heavy Ion Beam Operation at FAIR Intensities J2 - Proc. of LINAC2022, Liverpool, UK, 28 August-02 September 2022 CY - Liverpool, UK T2 - International Linear Accelerator Conference T3 - 31 LA - english AB - The GSI-UNILAC as well as the heavy ion synchrotron SIS18 will serve as a high current heavy ion injector for the FAIR synchrotron SIS100. In the context of an advanced machine investigation program acceleration and transport of space charge dominated argon beam inside entire UNILAC have been explored. The conducted high current argon beam measurements throughout the UNILAC-poststripper and transferline to SIS18 show a transversal emittance growth of only 35% for the design current of 7 emA (40Ar¹⁰⁺). By horizontal collimation of the UNILAC beam emittance, the space charge limit could be reached at slightly lower pulse currents, but accordingly longer injection times. Further improvements in brilliance can be expected from the planned upgrade measures, in particular on the high-current injector linac.
