As the analysis of modern monographs and review materials in recent years shows, the development of oscillators and amplifies in the terahertz range is one of the most important problems of modern radio engineering.  In the centimeter wavelength range, magnetron-type generators and amplifiers have proven themselves well due to their compactness, resistance to climatic, mechanical, and radiation loads. However, in the transition to the terahertz range (wavelengths of 1 mm and less), almost insurmountable difficulties occur due to the need for super precision manufacturing of multi-cavity anode structures, as well as their cooling. In order to overcome these problems, the authors propose to use the hypothesis of P.L. Kapitsa about the possibility of generating electromagnetic energy in the absence of a multi-cavity anode structure, namely, in the interaction space formed by a coaxial resonator. The paper presents a mathematical model of the magnetron current generator, which makes it possible to calculate the charge trajectory, induced currents, generation power at a frequency of 300 GHz. It is concluded that it is possible to further increase the generation frequency.
