Abstract

We use a continuous neutral density attenuator to investigate the photomultiplier tube (PMT) charge nonlinearity which exists in the PMT response to external signals to be measured. The results show that this testing approach provides a reliable and practical method for characterizing the PMT nonlinearity, enabling optimization of the operation conditions and improving the measurement accuracy of PMT by mitigating the nonlinearity. This study helps to advance the research and measurements in the related fields using a PMT.

利用连续光衰减法测量 PMT 电荷非线性度

我们使用连续中性密度衰减器来研究光电倍增管（PMT）电荷非线性，这种非线性存在于光电倍增管对外部待测信号的响应中。结果表明，这种测试方法为确定光电倍增管非线性特性提供了一种可靠而实用的方法，可以优化操作条件，并通过减轻非线性提高光电倍增管的测量精度。这项研究有助于推动使用 PMT 进行相关领域的研究和测量。
