微通道板輸出電極的最佳深度
THE OPTIMUM OUTPUT ELECTRODE DEPTH OF MCP
-
摘要: 本文給出了微通道板(MCP)輸出電極的最佳深度表達式。在此最佳條件下,MCP輸出電子能量分布(EDOE)曲線只有銳的低能主峰,它的半寬度達到極限值,能在極限空間分辨率下工作。解釋了以前所報道的MCP的EDOE特性,那實際上是偏離最佳條件下的MCP的特性。

Abstract: 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. -
