摘要
背景噪声是造成二代像管成品率低的重要因素 ,微通道板产生的噪声是二代像管背景噪声的主要来源 ,该文分析微通道板的主要噪声来源 ,阐明产生光子散射和电子散射的机理 ,通过对微通道板输入表面采用扩口技术 ,提高微通道板的开口面积比 ,降低微通道板的噪声 ,提高其分辨率 。
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. This paper discusses the main noise of MCP,describes the principle of phones scatter and electron scatter,and presents the method of reducing scatter noise and improving resolution. It will provide a theory foundation for further craft research.
