Radio frequency generator for ion propulsion (RFG)

Ion Propulsion systems (IPS) as the RITA produce thrust by accelerating ions extracted from a plasma. For the RITA this plasma is generated by a rf-ionization process. The Radio Frequency Generator (RFG) is the key element to initiate and sustain the plasma discharge by controlling the rf-power. Furthermore the RFG control directly the thrust level of the IPS
