摘要
本文给出了微通道板(MCP)输出电极的最佳深度表达式。在此最佳条件下,MCP输出电子能量分布(EDOE)曲线只有锐的低能主峰,它的半宽度达到极限值,能在极限空间分辨率下工作。解释了以前所报道的MCP的EDOE特性,那实际上是偏离最佳条件下的MCP的特性。
The expression for the optimum output electrode depth of MCP is given. At optmum operation of MCP, the energy distribution curve of the output electron (EDOE) only shows a low energy sharp main peak, its FWHM is reduced to lower limit, and MCP can operate up to its upper spatial resolution limit. The properties of the EDOE from MCP are explained successfully
