In this work, the negative ion source Prometheus I, installed in the University of Patras, is presented. The plasma is sustained by five dipolar electron cyclotron resonance sources and characterized by means of electrostatic probe and laser photo-detachment technique. The source configuration and the installed diagnostic techniques are herein discussed. Indicative results of the plasma produced are then analyzed. Hot and cold electron populations are generated and negative ion densities in the order of magnitude 10^9 cm^-3 are measured for the conditions tested.
