description: This thesis is in the context of study and design of a new ECR light ion source on LEDA (Laboratory of Research and Development of Accelerators - CEA Saclay), named ALISES (Advanced Light Ions Source Extraction System). As a first step, the magnetic, electrical and mechanical design of the new source is described. Then, simulations were performed to determine the reduction of emittance growth taking into account the reduction of the length of the LBE (Low Energy Beam Line) provided by the source ALISES. With this source, it’s also possible to realize a study on the dimensions of the cylindrical plasma chamber. Simulations were performed to better understand the interaction between radiofrequency wave and plasma. Subsequently, experiments on the source ALISES helped highlight, understand and solve problems in the Penning discharges inside the accelerator column. Measurements performed on the plasma have yielded the assumption that the electrons are heated at the entrance of the plasma chamber and thermalized along its entire length to achieve an energy corresponding to the maximum of the ionization cross section for hydrogen.
