Abstract


Temperature dependence of the auxiliary cathode emission current in magnetrons with cold secondary-emission cathodes is investigated theoretically. Different methods of providing a spatial-charge limited emission from the auxiliary cathode are studied to eliminate the temperature dependence. A new design of the auxiliary cathode is proposed which is supposed to provide a better temperature stability as compared to that used in currently manufactured magnetrons.
