Abstract :
Summary form only given. In the two-beam klystron, two annual electron beams propagate through a grounded drift tube. These beams are premodulated at the first cavity by input microwaves. When portions of these beams arrive on the second cavity, modulated current in the outer beam excites the cavity, which reflects some segments of the inner beam and sends them back to the first cavity. Modulated current in the return beam further excites the first cavity, if it is in phase with the cavity oscillation. Formation of a virtual cathode at the location of the second cavity and return current is essential for the two-beam klystron to work. A theoretical model of the two beam klystron has been developed.
