Diagram: Geoneutrinos (IMAGE) Forschungszentrum Juelich Caption The diagram shows geoneutrinos from the earth's interior measured by the Borexino detector, resulting in the final energy spectra. The x-axis shows the charge (number of photo electrons) of the signal, which is a measure of energy deposited in the detector, and the y-axis shows the number of measured events.
