Abstract
A method for reducing electron emission of an electron emitter comprises: emitting electrons from a first current path via at least one first field effect emitter element, subject to an emission voltage between a gate electrode and an emission surface; determining a property of the first current path; and activating a first current limiting unit subject to the properties of the first current path to reduce the electron emission of the electron emitter.
