INVESTIGATION OF LINEAR BEAM AND NEW CONCEPTS OF MICROWAVE POWER. VOLUME IV. NANOSECOND PULSE STUDY,

Abstract

A theory based on an idealized model and including space charge explicitly is developed for the nonlinear behavior of an electron beam velocity-modulated by an ideal gap and of finite cross section filling a conducting cylinder. A strong axial magnetic field allows the motion of electrons in the axial direction only. An expression for the current density has been derived using a method of successive approximations. Starting from the known solution for the infinite beam, successive approximations have been considered to take account of the finite radius of the beam. The axial component of the electric field as a function of r and z has been evaluated. (Author)
