Borexino open data is a selection of experimental data acquired and analysed by the Borexino collaboration for some of the Borexino publications which has been made freely available to anyone interested. You can find the data – together with a description – in the corresponding posts in the “Open Data” category on this site (check the “contents menu” on the dide or click here).  Feel free to comment or to ask for clarifications.


Borexino is a particle physics experiment located in Hall C of the Laboratori Nazionali del Gran Sasso, approximately 150 km north-east of Rome, Italy. It is a large liquid scintillator detector whose main goal is the study of the properties of low energy solar neutrinos. Data-taking begun in 2007. The exceptional levels of radiopurity Borexino has reached through the years have made it possible to accomplish not only its primary goal but also to produce many other interesting results both within and beyond the Standard Model of particle physics.

The Borexino experiment is performed by an international collaboration featuring about 140 scientists from:

  • Italy (INFN and Universities of Milano, Ferrara, Genova, Perugia, INFN Laboratori Nazionali del Gran Sasso, Politecnico di Milano and GSSI);
  • France (CEA Saclay and APC Paris);
  • Germany (TUM München, MPI-K Heildelberg, TU Dresden, Forschungszentrum Jülich, Universities of Tübingen, Hamburg, and Mainz);
  • Russia (JINR Dubna, Lomosonov State University, Kurchatov Institute Moscow and NPI St. Petersburg);
  • Poland (Jagellonian University Krakow);
  • Ukraine (Kiev INR);
  • United States (Universities of Princeton, Hawaii, Massachusetts Amherst, Houston, UCLA and Virginia Polytechnic Institute).
