High-Current Proton Beam Investigations at the SILHI-LEBT at CEA/Saclay

The future proton LINAC at GSI for FAIR requires that the ion source and the low energy beam transport system deliver a 100 mA proton beam with an energy of 95 keV within an acceptance of 0.3 mm mrad (normalized, rms) at the entrance of the RFQ. Between the ion source and the RFQ a 2-solenoid focussing system is foreseen. The beam parameters of the present SILHI ion source (Source
