硅光电倍增器的后脉冲效应对光电探测器特性的影响

Afterpulsing in Silicon Photomultipliers: Impact on the Photodetectors Characterization

Adam Para

摘要:

新一代硅基光电探测器是传统光电管的有吸引力的替代品。它们提供了巨大的优势,但也带来了新的挑战。后脉冲的存在会影响光电探测器的许多特性。简单的统计模型的afterpulsing是用来评估所观察到的暗计数率的贡献,检查的脉冲高度分辨率的贡献,并证明所观察到的SiPM的定时特性的修改。

英文摘要:

Novel generation of silicon-based photodetectors are attractive alternatives to the traditional phototubes. They offer significant advantages but they present new challenges too. Presence of afterpulses may affect many characteristics of the photodetectors. Simple statistical model of afterpulsing is used to evaluate the contribution to the observed dark count rates, to examine the contribution to the pulse height resolution and to demonstrate the modification of the observed timing properties of the SiPMs.
