description: The given work is devoted to studying of the gyrotron operation in the regimes with improved electron beam quality. Tasks that were solved in the course of the study: 1. Modernization of the experimental gyrotron of SPbPU. The equipment of the gyrotron collector with a magnetic system designed for implementation of multi-stage recovery of residual energy of the electron beam in this device. 2. Experimental study of the possibility of increasing the efficiency of the upgraded gyrotron in the regimes with increased HEB quality, which are characterized by suppressed parasitic low-frequency oscillations, reduced velocity spread and increased pitch factor, achieved with optimized distributions of electric and magnetic fields. The work was fulfilled using the SPbPU gyrotron with an output radiation wavelength of 4 mm and an output power of ~100 kW, equipped with a set of diagnostics for determining the parameters of the electron beam. As a result, at optimal distributions of the electric and magnetic fields, stable generation was provided at the operating mode TE12,3 in the absence of parasitic low-frequency oscillations with a maximum gyrotron efficiency of approximately 46 %.
