Engineering Physics Annotation << Back Modeling the Motion of Charged Particles at Various Stages of the Evolution of the Current Sheet Fomichev O.V., Andreev S.Ye. For the «Current Sheet» CS-3 setup (GPI RAS), a three-dimensional magnetic fi eld configuration was modeled, and electron motion trajectories were obtained at various stages of the current sheet evolution. The current sheet was modeled using the Drude model. Depending on the energy of the electrons emitted by the cathode, both their drift to the chamber wall and capture in the current sheet were obtained. A qualitative change in the nature of charged particle motion during the time evolution of the current sheet was demonstrated. Keywords: current sheet; numerical simulation; trajectory; particle.
