Year: 2023
Type: article
Abstract: The paper presents an experimental method for determining the power of microwave/HF losses in the city of a toroidal resonator of a prototype accelerator ion thruster. The method is based on the analysis of the fundamental frequencies present in the resonator when it is excited by a solid-state oscillator. The advantage of the method is its invariance to the optical radiation of a high-frequency discharge and thermal effects in plasma. The method of frequency analysis showed that the main frequency of the autogenerator in the cavity of the toroidal resonator creates an alternating accelerating voltage of 276.7 V. At the same time, the power of the main frequency when a discharge occurs increases by 145 times with an increase in the energy consumption of the prototype by 1.8 times. A frequency close to the resonant frequency of the resonator creates an accelerating voltage of 50 V.
