“…When the electron beam is ideal, the W-band sixth-harmonic peniotron can have 30 kW output power and the conversion efficiency is 40%. 7) The effect of the peniotron guiding center deviation is shown in Fig. 6, which shows that with the increase in the amount of deviation, the output power and conversion efficiency of peniotrons slowly decline.…”

A calculation code for a self-consistent nonlinear large signal of peniotrons has been developed in this study. A PIC simulation of a W-band sixth harmonic peniotron with an ideal electron beam has shown 30 kW output power and conversion efficiency of up to 40%, which agree well with the results obtained under the peniotron self-consistent nonlinear large-signal calculation code. Thus, the code can be used to study peniotron performance when effects such as electron velocity spread and guiding center deviation exist. Calculated results show that a 10 kW microwave output power and a conversion efficiency of 17% can always be obtained if the peniotron guiding center deviation and longitudinal velocity spread are no more than 8%. These results help determine the minimum requirements of the electron beam quality in W-band practical peniotrons.
