Petrushenya A. Formation and dynamics of negative charged particles in plasma electromagnetic traps.

The physical processes of creation and dynamics of electrons and negative ions in plasma sources on the basis of a penning trap, as well as a cusp electromagnetic trap have been studied. The features of the axial evolution of energy specters of an electron beam ejected from a plasma sources based on a penning trap have been determined. It has been proposed a new method to control the current of the ejected electron beam. The features of emission and discharge characteristics of a penning plasma electron source of with a hollow cathode have been studied under using of an electrically asymmetric circuit between cathodes and operation gases with various mass numbers. The possibility of the generation of negative ions in a plasma source based on a single-cusp electromagnetic trap with a plasma source of electrons has been demonstrated.
