Abstract
Microchannel plates having increased gain and significantly improved aging characteristics are provided by forming a thin film of a cesium compound on the channel walls. In an exemplary embodiment, a surface film of cesium hydroxide is applied to the interior wall surfaces of an MCP by saturating the plate with a solution of the compound, then allowing the solvent to evaporate. The cesium hydroxide residue on the walls subsequently is converted to cesium oxide by a high temperature bake.
Claims3
In a microchannel plate comprising a multiplicity of elongate tubular channels formed of a lead-containing glass, each such channel including a secondary electron-emissive interior wall surface region, the improvement comprising the inclusion of cesium oxide in said region in an amount sufficient to increase the gain and improve the aging rate of said plate.
A microchannel plate comprising a multiplicity of elongate hollow channels formed of lead-containing glass, each of said channels including a secondary electron-emissive interior wall surface region, characterized in that a stable cesium oxide is incorporated into said surface regions in an amount sufficient to stabilize the gain characteristics of said channels.
