High Current Uranium Beam Measurements at GSI-UNILAC for FAIR

In the context of an advanced machine investigation program supporting the ongoing UNILAC (Universal Linear Accelerator) upgrade program, a new uranium beam intensity record (≈10 emA, U) at very high beam brilliance was achieved last year in a machine experiment campaign at GSI. The UNILAC as well as the heavy ion synchrotron SIS18 will serve as a high current heavy ion injector for the new FAIR (Facility for Antiproton and Ion Research) synchrotron SIS100. Results of the accomplished high current uranium beam measurements applying a newly developed pulsed hydrogen gas stripper (at 1.4 MeV/u) will be presented. The paper will focus on the evaluation and analysis of the measured beam brilliance and further implications to fulfil the FAIR heavy ion high intensity beam requirements.
