The Accelerateur d'Ions Multicharges (AIM) - a facility of the CEA-Grenoble - is open to users who need high intensity beams of highly charged ions. Within the last years, efforts were undertaken to enhance the performance of the source as well as the quality of the beam transport. Some of these improvements concern the change to a 14.5 GHz ECR ion source, the shortening and optimization of the beam transport and an improved pumping of the extraction region. The ions are extracted with a static field from the source, ion beam energies in the range of (1-20) keV per charge are currently attainable. The typical performances of the source for stable operation over long time are, e.g. 1.1 mA O8+, 24 nA Ar17+ and 400 nA Xe30+. This allows us to deliver beams of small divergence (20 p mm mrad) to the five user beam lines of 600 nA O8+ and 4 nA Ar17+ at beam energies of 20 keV per charge. The current setup of the accelerator and future enhancements of the performance will be discussed.
