Abstract
A traveling-wave tube system and a method for protecting a cathode of a traveling-wave tube system. The system has an electron gun and a power supply that applies an electric potential between a cathode and an anode of the electron gun to generate a beam of electrons. The beam of electrons passes through a passage of a slow-wave structure. A collector electrode collects electrons from the beam of electrons generating a flow of current that flows through an ion trap power supply circuit to generate a DC voltage that is applied to the anode to repel positive ions generated.
