N-BEAM NONLINEAR TRAVELING-WAVE AMPLIFIER ANALYSIS
Abstract
An approximate method was used to study the effect of transverse electric field variations on the gain and efficiency of large-signal travelwave amplifiers. The annular electron stream is subdivided into a number of annular rings each containing and equal fraction of the total current. It is assumed that the circuit field varies over the stream cross section and that each segment has a different coupling to the circuit. The space-charge field is assumed independent of radius. The effect on gain and efficiency is calculated for a stream diameter of B equals 1 and it is found that a subdivision of the stream into 2 segments with different couplings to the circuit gives a lower saturation efficiency but that further subdivision does not appreciably change the results.
