Throughout its history, KM3NeT has received support from the European Union, via participation in several European projects, but also by the acknowledgement of the value of KM3NeT by the European institutions.

In 2006 KM3NeT was included in the European Strategy Forum on Research Infrastructure (ESFRI) roadmap, which recognises the KM3NeT research infrastructure for Europe’s scientific needs for the next 10-20 years. The support was renewed by the Council of the European Union for the 2019-2026 period. While the first phase of the project led to the engineering of the modular detectors and the construction of prototypes, the objective of KM3NeT 2.0 is to adapt to the scientific and technological progress made in the field of neutrino astroparticle physics. Therefore, the second inscription in the ESFRI roadmap reaffirms the interest of KM3NeT during its effective construction phase.

Along with the Council, the implementation of KM3NeT installation sites also benefitted from funding through the European Regional Development Fund (ERDF), confirming the economic, social and territorial potential of KM3NeT at regional level.

The European projects led by the Collaboration as well as those in which KM3NeT has participated are described on these pages:

  1. KM3NeT Design Study
  2. KM3NeT Preparatory phase
  3. KM3NeT-INFRADEV
  4. KM3NeT-INFRADEV2
  5. KM3NeT participation in other European projects
