摘要： A field emitter for producing an electron beam includes at least one cold cathode unit. Each of the cold cathode units includes an emitter cone having an emitter tip and a gate spaced apart from the emitter tip for extracting electrons from the emitter tip in a propagation direction upon application of a positive dc voltage on the gate with respect to the emitter tip. The gate forms a gate cavity for propagation of the extracted electrons therethrough. Each of the cold cathode units further includes at least one lens electrode disposed further in the propagation direction from the emitter tip than the gate, the at least one lens electrode forming at least one lens cavity for propagation of the extracted electrons therethrough. The at least one lens electrode is for focusing the extracted electrons in part of the gate cavity, part of the at least one lens cavity, and part of the region therebetween.

摘要： 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.

摘要： The present invention is a device for producing collimated electron beams. The device comprises a gated field emission array having at least one emission tip and a grid electrode having a grid opening disposed above the emission tip in a first direction. The device also comprises an integrated planar lens electrode for producing a focusing effect on electron beams emitted by the emission tip. The planar lens electrode has a lens edge disposed aside at a distance from the grid opening in a second direction perpendicular to the first direction. Preferably, the planar lens electrode is an integrated layer with the gated field emission array on a substrate. The grid electrode and the lens electrode can be on the same layer and separated by a gap of vacuum. The planar lens electrode can be above the grid electrode, separated by an insulative material. Similarly, the planar lens electrode can be below the grid electrode, and separated by an insulator material. Sometimes, the base electrode on which the tips are formed can act as a lens.
