Abstract

In this paper, the influence of the microchannel plates (MCP) opening area ratio (OAR) and secondary electron emission (SEE) coefficient of SEE layer on the noise factor of image intensifier tube have been studied. According to the experiment, the influence percentage of MCP OAR and SEE coefficient of MCP SEE layer on noise factor reduction has been obtained. A MgO SEE layer with SEE coefficient of 4.5 was coated on the MCP input side with an OAR of 68%. After being assembled as an image intensifier, the noise factor of MCP decreases from 1.638 to 1.096, and drop 33.0%, which laid a good foundation for improving the signal-to-noise ratio of image intensifier.
