We present the results of the Hamamatsu R5912 photomultiplier tube modelling and simulating. The model can be adapted to any photomultiplier architecture by changing the number of electrodes, voltage distribution, and intrinsic PMT parameters. Our approach solves the use of tapered voltage dividers and allows photomultiplier simulations under stimulation conditions. The model implementation is not limited to SPICE-based software but also be used with compiled and interpreted programming languages. The modeled pulse charge of a vertical muon differs about 4% from the data. The resistive divider model tested reproduces the voltage distribution along the dynodes with a variance of ~3.5%. We compare the photomultiplier model linearity with the data from the operating LAGO's (Latin American Giant Observatory) water Cherenkov detectors installed at Bucaramanga-Colombia and Bariloche-Argentina.

LAGO 项目 R5912 光电倍增管的建模和仿真


我们展示了 Hamamatsu R5912 光电倍增管建模和仿真的结果。通过改变电极数量、电压分布和固有 PMT 参数，该模型可以适应任何光电倍增管架构。我们的方法解决了锥形分压器的使用问题，并允许在刺激条件下进行光电倍增管模拟。该模型的实现不仅限于基于 SPICE 的软件，还可以与编译和解释的编程语言一起使用。垂直 μ 子的模拟脉冲电荷与数据相差约 4%。测试的电阻分压器模型再现了沿倍增电极的电压分布，方差约为 3.5%。我们将光电倍增管模型的线性度与安装在哥伦比亚布卡拉曼加和阿根廷巴里洛切的正在运行的 LAGO（拉丁美洲巨型天文台）水切伦科夫探测器的数据进行比较。
