论文摘要

江门地下中微子天文台（JUNO）是中国南部建筑阶段的下一代液体闪烁体中微子实验。得益于附近核电站产生的抗神经，Juno将主要研究中微子质量等级，这是中微子物理学中的开放关键问题之一。测量成功的一种关键要素是使用位于检测器信号的高速，高分辨率采样电子设备。电子设备响应中的线性性在另一个重要的实验成功成分中。在电子设备的初始设计阶段，具有非常接近检测器模拟信号的前端和读出的电子设备的定制设计已开发并成功测试。本文描述了电子结构以及对原型进行的首次测试。电子原型已经进行了测试，它们显示出良好的线性响应，在整个动态范围内（1-1000 P.E.），最大偏差为1.3％，满足Juno实验要求。

Jiangmen Underground neutrino Observatory (JUNO) is a next generation liquid scintillator neutrino experiment under construction phase in South China. Thanks to the anti-neutrinos produced by the nearby nuclear power plants, JUNO will primarily study the neutrino mass hierarchy, one of the open key questions in neutrino physics. One key ingredient for the success of the measurement is to use high speed, high resolution sampling electronics located very close to the detector signal. Linearity in the response of the electronics in another important ingredient for the success of the experiment. During the initial design phase of the electronics, a custom design, with the Front-End and Read-Out electronics located very close to the detector analog signal has been developed and successfully tested. The present paper describes the electronics structure and the first tests performed on the prototypes. The electronics prototypes have been tested and they show good linearity response, with a maximum deviation of 1.3% over the full dynamic range (1-1000 p.e.), fulfilling the JUNO experiment requirements.
