摘要
本文明确指出,利用极值条件,通过测量MCP的极值增益,可方便准确地确定MCP通道内壁二次电子发射材料的特征常数A及其发射的二次电子的平均初始能量(动能)V_0。从而可准确设计、制造满足特定要求的MCP。
The present article shows that the secondary electron emission material constant A on the channel wall of MCP and the average emission potential V0 of the secondary electrons at right angles to the wall can be conveniently determined by means of the measurement of extreme gain of MCP. The determination of A and V0 is usefull to select the materials, structures, and schedules of manufacturing MCP, as well as operating modes of MCP.
