| The Microchannel plane (MCP) is an electron multiplier, which is the core component of the low-light-level (LLL) image intensifier. Double-side Polishing is an important technics in the process of MCP manufacture. In this thesis, the attention is focused on studying the micro-appearance and structure of MCP surface with high resolution optical microscope and scanning electron microscope. The effect of the chemical erosion to surface quality of MCP is analyzed in the process of double-side polishing. According to the experiment result, choosing the appropriate PH value polishing liquid and additive can obtain the MCP which has high quality surface roughness, meanwhile, it can reduce the surface qualitative disfigurement such as nick, which effectively increase the rate of good products in the MCP manufacturing. |
