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，我们看到了中微子物理学的实质性进展。最紧迫的问题之一是解决关于中微子质量本征态排序的不同假设。解决这个问题是朱诺项目的首要目标。此外，该实验还将解决部分天体物理(即超新星观测)、地球物理(地球中微子)和粒子物理(即质子衰变)中的一系列有趣问题。朱诺探测器正在广东省中国南部建造。它是一个2万吨液体闪烁体探测器，基于Borexino和Double Chooz技术以及Lena项目的开发。自2016年1月以来，DFG研究单位为朱诺的技术发展做出了重大贡献。在第二个供资期间，我们希望完成这些发展，并越来越多地把重点放在重建事件和准备数据分析上。
