This work deals with a first investigation of density profiles in a glow discharge with a magnesium cathode. Magnesium is detected by laser-induced fluorescence and spatial profiles can be recorded by moving the observation volume along the axis of the discharge, which burns in helium. After a brief description of the experimental arrangement, the electrical characteristics and emission line profiles, which both help to define the operating conditions of the discharge and so set up the frame for the laser measurements, are discussed. Finally, preliminary fluorescence profiles are presented.
