Estimate of electron efficiency of a TWT with logarithmic spiral
Abstract
The energy method is used to obtain an estimate of the length of the saturation space and the electron efficiency of a planar traveling wave tube in which the radially diverging electron current moves in a logarithmic spiral. The energy given by a single electron to the HF field is calculated by integrating the equation of motion of an electron; the average power delivered by a single electron is obtained by averaging over all the flight phases. Although a detailed investigation of the influence of the parameters was not carried out, it is shown that an increase in the input signal significantly reduces the saturation length, and the presence of a maximum efficiency is observed.
