Abstract (en)
In a tube such as an IOT, an electron gun includes a cathode (2), grid (3) and an anode (4) surrounded by a resonant input cavity (5). A grid lead (10) supplies a voltage to the grid (3) and includes a filter comprising a capacitor (11) and inductor (12) which are both approximately one quarter wavelength long at a selected frequency to reduce or prevent rf leakage along the grid lead (10). The grid lead (10) is arranged to extend through the cavity (5) and is located within the interior space (7) which is surrounded by the outer part (6) of the annular cavity (5).
