ABSTRACT:
A crossed-field amplifier is provided having a cathode structure with an emitting surface which emits secondary electrons upon impingement of priming electrons, an anode vane structure surrounding the cathode and a signal input port located adjacent the anode vanes. A secondary emission material is disposed in an area proximate the signal input port for providing priming electrons in the interaction region of the amplifier. The RF input signal causes the secondary emission material to emit priming electrons for use by the cathode structure. The creation of priming electrons in the interaction area reduces irregular start-up or "jitter" typically experienced with the amplifier at low pulse repetition frequencies.
