The space charge limiting current in a wave cavity and in presence of electromagnetic fields is calculated in connection with application to high power gyrotrons. It is found that the ponderomotive energy alters radically the build up of beam electrostatic energy. As a consequence, the limiting current can be greatly decreased or enhanced depending on whether the ponderomotive energy is positive or negative, respectively. This effect can be observed experimentally and it has important practical consequences for present high-current particle beam experiments.
