Каразіна Description The research focuses on development of mathematical models and computational methods of excitation processes and modulation instabilities of the intense wave field in plasma electronics devices. Unlike vacuum systems, the use of plasma electronics devices makes it possible to change the frequency of radiation in a wide range, to create more compact devices, to accelerate beams to high energies at small distances, to transport bunches of high density and high current. However, the creation of plasma electronics devices is associated with significant problems, for example, with the difficulty of choosing an operating mode and determining the efficiency of oscillation output in a multimode mode, ensuring stability of oscillation radiation, with the presence of noise, etc. On the basis of the simulation results, the initial conditions of mathematical models were determined for enough accuracy of the numerical experiments of work points search for beam-plasma generators and the determination of the conditions for the ions heating. Such conditions not given in the literature are sufficient for the accurate description of the plasma by the hybrid method in the one-dimensional case. popup.nrat_date 2026-04-13 Close
