We have seen a substantial progress in neutrino physics during the past years. One of the most pressing questions is the resolution of the different hypothesis on the ordering of the mass eigenstates of the neutrinos. The resolution of this question is the prime objective of the JUNO project. In addition, the experiment will address a series of interesting questions in parti-cle astrophysics (i.e. supernova observations), geophysics (geoneutrinos), and particle physics (i.e. proton decay).The JUNO detector is under construction in southern China in the province of Guangdong. It is a 20 kt liquid scintillator detector based on the technologies of Borexino and Double Chooz and the developments for the LENA project. Since January 2016, the DFG research unit contribut-ed substantially to the technical developments for JUNO. In the second funding period, we want to complete these developments and focus more and more on the reconstruction of the events and the preparation of the data analysis.

在过去的几年里，我们已经看到中微子物理学取得了实质性进展。最紧迫的问题之一是解决有关中微子质量本征态排序的不同假设。解决这个问题是JUNO项目的首要目标。此外，该实验还将解决粒子天体物理学（即超新星观测）、地球物理学（地中微子）和粒子物理学（即质子衰变）中的一系列有趣问题。JUNO探测器正在中国南方的省份建造。粤。它是基于 Borexino 和 Double Chooz 技术以及 LENA 项目开发的 20 kt 液体闪烁体探测器。自 2016 年 1 月以来，DFG 研究单位为 JUNO 的技术开发做出了重大贡献。在第二个资助期，我们希望完成这些开发，并越来越关注事件的重建和数据分析的准备。
