Abstract: The present invention relates to electronics and particularly to field emitters used in M-type microwave devices. The design of a multi-layer field emitter is proposed which has at least one operating film and supporting films, providing mechanical strength and preventing penetration of corrosive materials into the operating film at high operating temperatures. The supporting films could be produced from the same material or material with linear expansion coefficients equal or close to that of the operating film material. Built-in mechanical stress can cause not only deformation but also a break of the film during its exploitation in a wide range of temperatures. In the inventive structure the thermal stresses in the operating film during an emission from its surface are lower due to good thermal contact with supporting films.

Abstract: When high luminance is obtained by increasing an anode voltage in an image-forming apparatus constructed by anode and cathode substrates, a surface discharge (flash over) is generated between anode electrodes at a generating time of an abnormal discharge and an anode is broken. Therefore, as shown in FIG. 3B, the electric potential of an anode electrode on an anode substrate (51) is set to a uniform electric potential V1 by a first power source (53). Thereafter, the first power source (53) is separated from the anode electrode. Subsequently, the electric potential of one of the anode electrodes arranged in proximity to each other through an insulating face is set to an electric potential V2 by a second power sourced (54) to apply a voltage to a cut-in portion (52) (see FIG. 3C). Thus, a voltage Vc equal to or greater than an electric potential difference Ve generated at the generating time of the abnormal discharge is applied to the cut-in portion (52).
