The various controls necessary to characterize cesium ion thrusters are presented. The following metrological process was developed by the ONERA: control of the thermal equilibrium and regulation of the temperature of the ionizer and of the cesium supply device, control of the ion current emission characterized both globally and locally, control of the ionization yield by the determination of the number of neutral cesium atoms by means of an appropraite detector, and analysis of the structure of the beam by mapping the ionic current density. This characterization is completed by the results of cyclic regime tests runs reproducing the working conditions in satellite.
