ABSTRACT:
2. In a reflex klystron tube apparatus, means for forming a beam of electrons, a resonator means positioned along the beam path, said resonator means being apertured for the passage of the beam of electrons therethrough for electromagnetic coupling to the beam, reflector means disposed on the side of the resonator remote from said means for forming the beam of electrons, said reflector means serving for reflecting the electrons incident upon the reflecting fields of said reflector means back through said resonator means substantially along the incident beam path, said means for reflecting the electrons formed and arranged to impart a slight transverse velocity to the electrons whereby they are caused to move transversely of and out of the beam in a small number of beam transits thereby minimizing unwanted amplitude and power modulation in the output signal of the tube apparatus.
