摘要

The objective of Part I was to develop and to provide for experimental verification of a design technique for reducing spu rious output signals in high-power klystrons, and thus to provide a practical method for the reduction of spurious-output signals in high-power radar transmitters where the power amplifier is a klystron. The study included: (1) the definition of the particular electromagnetic compatibility problem, (2) a solution for the problem, and (3) the design and construction of a high-power, hot-test facility for measuring spurious output signals. The problem of space-charge wave propagation along a scalloped Brillouin beam is investigated in Part II both by analysis and experiment. The major result of the analysis is the description of the r-f currents and velocities in the beam by the solutions of Mathieu's Equation. Experimental evidence of both amplification and attenuation as well as of the locking phenomenon is presented and shown to agree with the predicted values. Effects of various parameters are discussed, and experimental data showing the effects of cavity position and magnetic field are presented as the bulk of the experimental work. (Author)
