Complex dynamics of coherent structures in two-stream vircator

Autors: 
Hramov Aleksandr Evgenevich, Immanuel Kant Baltic Federal University
Abstract: 

System of virtual cathode oscillators with electrostatic coupling-vircator оп oncoming streams is investigated with the aid of numerical simulation. The existence of different regimes, including the synchronisation and chaotic generation, is shown. Physical processes in the system are determined by the formation of electron patterns in each beam. The inner structures in the beam are analysed by the orthogonal decomposition by Karhunen-Loeve method. The simplest finite-dimension model-analogy is proposed to illustrate of аn interaction between electron structures in the beam, that leads to chactic dynamics of virtual cathode oscillation.
