The Borexino experiment is the first and only experiment that has successfully determined the flux of all the major components of the solar neutrino spectrum from the pp-cycle. However, for neutrinos originating from the CNO-cycle only an upper limit could be established so far. The primary goal of this project is the improvement of methods for the background rejection in order to make a determination of the CNO neutrino flux possible. In this context, we also plan to develop new methods of charged particle tracking in liquid scintillitator. With the measurement of the CNO neutrino flux, all solar neutrinos will be observed in a single experiment on an event by event basis for the first time, which will represent a milestone in experimental solar neutrino physics.Another part of the project is the use of a high intensity neutrino source at Borexino. The primary goal is the search for sterile neutrino oscillation on short baselines. Furthermore such a neutrinos source offers the opportunity to study fundamental characteristics of neutrinos such as a possible magnetic moment.

Borexino实验是第一个也是唯一成功确定来自PP循环太阳中微子光谱的所有主要成分的通量的实验。但是，对于源自CNO循环的中微子，到目前为止，只能建立上限。该项目的主要目标是改善背景排斥的方法，以确定CNO Neutmino通量。在这种情况下，我们还计划在液体闪烁体中开发带电粒子跟踪的新方法。通过对CNO中微子通量的测量，所有太阳中微子将首次在事件中进行单个实验中观察到，这将代表实验太阳中微子物理学中的里程碑。主要目标是在短基线上寻找无菌中微子振荡。此外，这种中微子来源提供了研究中微子（例如可能的磁矩）的基本特征的机会。
