    "abstract": "The effect of the strength of the focusing magnetic field on chaotic dynamic\nprocesses occurring inan electron beam with a virtual cathode, as well as on\nthe processes whereby the structures form in the beamand interact with each\nother, is studied by means of two-dimensional numerical simulations based on\nsolving a self-consistent set of Vlasov-Maxwell equations. It is shown that, as\nthe focusing magnetic field is decreased,the dynamics of an electron beam with\na virtual cathode becomes more complicated due to the formation andinteraction\nof spatio-temporal longitudinal and transverse structures in the interaction\nregion of a vircator. The optimum efficiency of the interaction of an electron\nbeam with the electromagnetic field of the vircator isachieved at a\ncomparatively weak external magnetic field and is determined by the\nfundamentally two-dimensional nature of the motion of the beam electrons near\nthe virtual cathode.",
