Annual Report 2020 published
The actual annual report of the IKP has been published and is available for download.
Description of the title page image:
Photo composition of the Sun, the Borexino detector - placed at the Laboratori Nazionali del Gran Sasso (Italy) - and the Earth. Borexino is a 280 ton liquid scintillator detector measuring neutrinos from the Sun and the Earth. The scintillation light is detected by an array of photomultipliers which are shown in the central part of the figure. In 2020, Borexino experimentally confirmed with high statistical significance the existence of the CNO fusion cycle in the Sun - paving the way towards the solution of the solar metallicity problem - and has also observed geoneutrinos emitted in the decay of long-lived radioactive elements inside the Earth - a new tool to understand the interior of our planet.
