Intense beam production with SuSI

SuSI ion source, a third generation fully superconducting ECR ion source is now used for ion beam injection to the Coupled Cyclotron Facility since September 2009. Initial performances during the commissioning of SuSI (Superconducting Source for Ions) were mainly limited by the microwave power available from a single 18 GHz microwave amplifier, especially for the production of heavier ion beams. The Injection of SuSI was modified to add a second 18 GHz amplifier, to reach a maximum of 3.0 kW of RF power inside the plasma chamber. Production of heavy ion beams, such as Kr14+, Bi30+ and U33+ is reported, to demonstrate the performance of SuSI. Additional studies were made with various ion source parameters to optimize the beam intensity within a normalized emittance of 0.9 pi.mm.mrad as needed for the FRIB project. The paper is followed by the slides of the presentation. (authors)
