  • Abstract
    Electron trajectories for a pencil beam are studied for both uniform and periodic magnetic fields. General equations are given which apply to shielded and unshielded cathodes and all intermediate cases. The balance conditions which yield minimum ripple solutions are presented as a function of magnetic field. It is shown that these conditions require that considerable magnetic flux thread the cathode for magnetic fields in excess of the Brillouin value
