Abstract :
The influence of RF-space charge on the beam-field interaction in gyrotrons is reviewed. This effect, formerly considered unimportant, is found to cause recognizable differences in simulations of gyrotrons with high current density, such as today´s megawatt level gyrotrons. In this paper, a numerically efficient way of including RF-space charge in the common slow variables model is derived and numerical examples are presented.
