AN INVESTIGATION OF THE LAMINARITY OF FLOW IN A MAGNETICALLY CONFINED ELECTRON BEAM

Abstract

A study of the electron flow in a Brillouin beam was made, which yielded information that provided an insight into the electron behavior in a medium-power Brillouin beam. It was shown that the beam can display a high degree of laminarity at a beam voltage of 5000. The trajectory equation of the outer edge electron in the laminar model of the beam was linearized and shown to give results in good agreement with the experimental observations, when the focusing field was less than twice the Brillouin field. It was also shown that the beam can be focused at the calculated Brillouin field within the limits of experimental error. The differences between the theoretical predictions and the experimental observations, which arose from limitations either of the experimental apparatus or the theory, are discussed. The effects of thermal velocities are considered particularly at low beam voltages.
