| Abstract: | Based on the theoretical analysis, the formula of MCP noise taecror is suggested. The results of numerical calculation show that the MCP noise can be reduced by increasing the yield of secondary electrons at MCP entrance. Accroding to this results, the possibility of reducing the noise factor by depositing certain alka lihalide compounds at the entrance of the MCP channels is discussed. |
