Abstract :
We discuss basic Relativistic Klystron Amplifier (RKA) physics. We show that, for pulse lengths of one microsecond or longer in the intense space-charge regime, the maximum power extraction from the beam does not coincide with the maximum harmonic bunching. We also discuss the beam-cavity interaction model and present experimental and theoretical single cavity modulation results. Finally, we discuss alternatives to the basic RKA design that enhance beam to microwave power conversion efficiency, particularly at high frequency.
