The work introduces information enabling optimization and standardization of an electrostatic plasma diagnostic known as Faraday Cup (FC). This instrument is used to accurately map in two or three dimensions the ion beam profile produced by an electric propulsion (EP) device [1, 2, 3, 4]. Results focus on the design of a Faraday cup in terms of probe aperture diameter, collection solid angle and material exposed to the ion beam. Additionally, modification of the equipotential field lines inside the probe are studied. The goal is to contribute to the effort towards repetitive and reliable determination of an EP device performance map (i.e. thrust, divergence angle, ionization efficiency and propellant utilization).
