Abstract

Background noise is an important factor that creates defective generation 2 image tubes. The main source of the background noise of generation 2 image tubes is the noise making from micro-channel plate (MCP). This paper discusses the main noise of MCP describes the principle of phones scatter and electron scatter, deduce the mathematics model of funnel shaped MCP, and presents the method which enlarges the micro-channel plate surface to increase the ratio of hatch area, reduce the scatter noise and improve the resolution of MCP. Process the experimentation of enlarging the surface of MCP. It provides a theory and practice foundation for farther craft research.
