description: The purpose of the work is to develop an experimental stand for a low-pressure HF plasma torch. To do this, the parameters of the generator lamp GU-5A were calculated. There are two main types of tube generators: with independent excitation and with self-excitation. Their main difference is that, when independently excited, vibrations are generated from the outside, the frequency of these vibrations is set by the source itself. During self-excitation, vibrations are generated directly inside the tube generators, and their frequency is set by the generator itself. During the calculations, the anode and grid characteristics of the tube generator were digitized. Later, these data were used to model the power supply in COMSOL Multiphysics, where graphs of the anode and grid voltage were obtained, as well as a suitable frequency (25.1 MHz) and plasma power in the load circuit (P=4.7 kW) were found. Later, using these values, as well as the construction of the plasma torch itself in COMSOL Multiphysics, plasma and electromagnetic field values were obtained. To be sure, it was decided to make calculations for different values of the source efficiency from 0.5 to 1. And from these calculations it was obtained that there is no plasma at an efficiency of 0.7 or less, and that the results cannot be physical.
