An experimental study and numerical modeling of the diocotron instability of high-current relativistic electron beams
Abstract
Experimental data on the transit of a relativistic electron beam in a tube and a coaxial conductor are compared with the linear theory of diocotron instability and with a numerical model based on the microparticle method. It is shown that the best agreement between experimental data and the model is obtained with the inclusion into the model of additional particle scattering. In experiments, such scattering may be produced by strong microwave fields in the drift space. The allowance for scattering in the model makes it possible to explain such an experimentally observed phenomenon as a decrease in the number of jets along the beam path.
