论文摘要
电荷响应的线性性是用于物理测量值的光电培养基管（PMT）的重要特征，尤其是新开发的20英寸MCP-PMT。在本文中，除了传统的双重光源方法外，我们还将20英寸PMT的另一种相对方法应用于3英寸PMT，以测量20英寸DONEDODE和MCT PMP PMT在脉冲模式中的线性，并具有脉冲模式。测量结果表明，良好的线性响应为20英寸至1,000个光电子。
The linearity of charge response is an important feature of photomultiplier tubes (PMT) for physics measurements, especially the newly developed 20" MCP-PMT. In this paper, in addition to the traditional method of double light sources, we applied another relative method of 20" PMT to 3" PMT to measure the linearity of the 20" dynode and MCP PMTs in pulse mode with a waveform digitizer. The measurements show a good linear response of 20" PMTs to 1,000 photoelectrons (p.e.). The correlations of the amplitude, rise-time, fall-time, FWHM, baseline recovery, overshoot, and late-pulse to the output charge of the 20" PMTs derived from the waveform analysis, where the MCP-PMT shows very different features compared to the dynode-PMT in particular.
