摘要

摘要基于微通道板的光电倍增管(MCP-PMT)的电子收集效率(CE)受到MCP开口面积分数的限制。用高二次屈服材料涂覆MCP被认为是提高CE的有效途径。开发了典型的MCP PMT和涂层MCP PMT。提出了一种相对测量方法来表征收集效率性能。结果表明,基于涂层MCP的PMT具有显著的CE改善、良好的增益均匀性和高精度的能量分辨率。

The Collection Efficiency of a Large Area PMT Based on the Coated MCPs
Abstract The electron collection efficiency (CE) of the photomultiplier tube based on microchannel plates (MCP-PMT) is limited by the MCP open area fraction. Coating MCP with a high secondary yield material is supposed to be an effective approach to improve CE. Both typical and coated MCP-PMTs are developed. A relative measurement method is proposed to characterize the collection efficiency performance. Results show that the PMT based on the coated MCPs has a significant improvement on CE, a good gain uniformity and a high precise energy resolution.
