摘要

背景噪声是造成第二代显像管缺陷的一个重要因素。第二代像管背景噪声的主要来源是微通道板产生的噪声。本文讨论了MCP的主要噪声，阐述了电话散射和电子散射的原理，推导了漏斗型MCP的数学模型，提出了增大微通道板表面以增加舱口面积比，降低散射噪声，提高MCP分辨率的方法。进行了扩大MCP表面的实验。为进一步的工艺研究提供了理论和实践基础。

The research of a funnel shaped micro-channel plate

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.
