The radio frequency Ion thruster uses a high-frequency electromagnetic field to ionize xenon gas atoms to form a plasma containing free ‘light’ electrons and ‘heavy’ positive ions. The heavy positive ions are then accelerated by an electrostatic field before being ejected to cause thrust.
After the ions have been ejected from the thruster, electrons are added from a neutralizer. The plasma is thereby neutralized which prevents the satellite from becoming charged.
RIT 10 EVO is the Radiofrequency Ion Thruster with medium thrust level based on the RIT 10 which has flown successfully and flawlessly over 10 years.
