An experimental and theoretical study has been made of the current neutralization during the injection of an intense relativistic beam with a length < or approx. =100 ns into an annular trajectory in a cylindrical chamber filled with air or a weakly ionized plasma in an external magnetic field. A numerical model is used to study the formation of a dense, toroidal plasma channel. The characteristics of this channel and of the plasma current are determined. The results found from the numerical model are compared with experimental data. Conclusions are drawn regarding the dynamics of the current neutralization and the conditions for the effective formation of annular relativistic electron beams in gases and plasmas.
