The article presents self-consistent models used at various stages of development of
powerful sources of electromagnetic radiation - gyrotrons. Methods for solving them are
presented, implemented in the ANGEL software package, which allows determining the
characteristics of the electrodynamic system, calculating the starting currents and the
efficiency of the electron-wave interaction.
