The Borexino Experiment research team has succeeded in detecting neutrinos from the sun's second fusion process, the Carbon Nitrogen Oxygen cycle (CNO cycle) for the first time. The findings are the result of years of efforts devoted to bringing the background sources in the energy range of the CNO neutrinos under control. Primarily bismuth-210 from trace impurities on the surface of the detector wall were responsible for concealing the signals of the CNO cycle. "The new Borexino results now support observations with higher metallicity values," says Prof. Lothar Oberauer of TUM.
