ABSTRACT:
An electron deflection device responsive to an electrical input signal for producing an output signal includes a focusing array for producing a collimated electron beam input ribbon in the direction of a propagation axis, the input ribbon being elongated along an array axis perpendicular to the propagation axis, and being relatively thin along a deflection axis perpendicular to the array axis and to the propagation axis. The focusing array is preferably a linear array of gated cold cathode units with lens electrodes. The deflection device further includes first and second electrically conductive deflector faces, forming a deflection region therebetween and being disposed so that the propagation-axis passes through the deflection region. The deflection device further includes means responsive to the input signal for applying time varying potentials to the deflector faces so as to produce a modulated electric field in the deflection region for deflecting the input ribbon over the course of a temporal deflection cycle to produce a continuously modulated output ribbon. The deflection device further includes an anode section responsive to the continuously modulated output ribbon for producing an output signal.
The output signal can be in the form of an electrical output signal or a chopped output ribbon suitable for input to a high power amplifier, such as a klystron, klystrode, traveling wave tube, distributed amplifier or a gigatron, or to a free electron laser.
