    Abstract: An apparatus for generating and focusing electrons is provided. The apparatus has an emissive material configured to emit an electron, an electron target, and an electrical potential gradient generator configured to generate an electrical potential gradient within the emissive material. The electrical potential gradient is oriented so as to vary from positive to negative in the general direction toward the electron target. In operation, an electron emitted from the emissive materials is deflected away from the emissive material and generally toward the electron target. The apparatus may be incorporated in scientific analytical equipment such as an electron multiplier.

    Abstract: An image intensifier and electron multiplier therefor is disclosed. Photons of an image impinge a photo-cathode that converts the photons to electrons. An electron multiplier multiplies the electrons from the photo-cathode to create an increased number of electrons. A sensor captures the increased number of electrons to produce an intensified image. The electron multiplier is an electron bombarded device (EBD) containing a semiconductor structure. The semiconductor structure has an input surface for receiving electrons and an emission surface for passing an increased number of electrons. The semiconductor structure is doped to direct the flow of electrons through the semiconductor structure to an emission area on the emission surface.

    Abstract: The cathode for photo-electron emission 5 is comprised of an alkali metal containing layer 5d made of material for emitting photo-electrons by the entry of light or for emitting secondary electrons by the entry of electrons, such as particles which consist of an alkali antimony compound, on an Ni electrode substrate 5c on which an Al layer 5b is deposited, and has an intermediate layer 5a made of carbon nano-tubes between the alkali metal containing layer 5d and the Ni electrode substrate 5c, therefore the defect density inside the particles is decreased, and the recombining probability of electrons and holes drops remarkably, which improves the quantum efficiency.
