Abstract
The present invention relates to a radioactive electron emitting microchannel plate. More particularly, to a radioactive electron generating microchannel plate comprising (a) a pair of parallel substrates; (b) at least one radioactive material layer deposited on an inner surface of the substrates; and (c) at least one electron ray-amplifying layer deposited on the surface of the radioactive material layer. The emitted electron ray is amplified by penetrating into the cavity formed by a pair of parallel substrates and is further amplified by reflecting from the electron ray-amplifying layer. As the substrate in the microchannel plate, use can be made of a capillary tube or a thin plate. The microchannel plate of the present invention can be applied as an electron ray source in an electron ray-generating device, an image display device, and electron ray-etching device.
