The ALISES ion source was originally designed to reduce beam emittance at RFQ entrance by shortened the length of the LEBT. A wide opened magnetic coil at ground potential produces the fringe field needed for the ECR heating at 2.45 GHz frequency. The first part describes the commissioning of the source: Penning discharges inside the accelerating column make the high voltage power supply collapse. Experimental tests with kapton films while discharges occur, and simulations with OPERA-3D code have shown great similarities to detect the location of those discharges and allow us to make the ion source work. The second part of this paper will present the result of low intensity light ion beam production versus the plasma chamber length and radius. Those very preliminary tests give us indications to reduce the ion source dimensions.
