Abstract:The conventional microchannel plate (MCP) detector has found
widespread application in various fields. This article focuses on
investigating the performance of a single MCP with a large
length-to-diameter ratio (L/D) of 80:1, particularly for single
electron counting. To enhance MCP performance, alumina with a high
secondary electron yield (SEY) is coated onto the MCP using atomic
layer deposition (ALD). The SEYs of alumina thin films with
different thicknesses are measured using a pulsing electr… Show more
