Abstract:
A method for making an improved microchannel plate, comprising:providing a microchannel plate being of a type formed from a substrate having an input surface, and output surface, and a plurality of channels extending therebetween for providing secondary emmission of electrons incident to said channels;forming an insulative film over the input surface and the channels of the microchannel plate;after forming the insulative film, depositing a fissured material onto the input surface of the microchannel plate, said fissured material having random fissures and being capable of secondary electron emission on the input surface of the microchannel plate and of causing a cascade of electrons for entry into said channels of the microchannel plate in response to an electron entering one of said fissures; andafter depositing the fissured material, removing the insulative film, whereby said fissured material does not penetrate into the channels.
