论文摘要
使用大量的光电塑料管（PMTS）开发了一个名为Catiroc（电荷和时间整合芯片）的ASIC（电荷和时间集成的芯片）。每个CATIROC都提供16个以无触发模式运行的16个可配置输入通道的时间和充电测量。我们最初是为水切伦科夫探测器中的光发射而设计的，我们在本文中表明，它的使用可以扩展到基于液体验证器的实验。 $ \ sim $ 26000 3英寸PMT的Juno实验是一个恰当的例子。本文描述了Catiroc的特征，并特别注意将其应用于液体闪光灯中光发射的时间曲线的最关键点。在充电和时间测量中，可以使用PMT或其他光敏探测器的将来的高精度实验的输入。
An ASIC named CATIROC (Charge And Time Integrated Read Out Chip) has been developed for the next-generation neutrino experiments using a large number of photomultiplier tubes (PMTs). Each CATIROC provides the time and the charge measurements for 16 configurable input channels operating in trigger-less mode. Originally designed for the light emission in water Cherenkov detectors, we show in this paper that its use can be extended to liquid-scintillator based experiments. The $\sim$26000 3-inch PMTs of the JUNO experiment, under construction in China, is a case in point. This paper describes the features of CATIROC with a special attention to the most critical points for its application to the time profile of the light emission in liquid scintillators. The achieved performances in both charge and time measurements can be inputs for future high-precision experiments making use of PMTs or other photo-sensitive detectors.
