The KM3NeT-INFRADEV2 project comes to an end

On the 31st of December 2025, the EU-funded project KM3NeT-INFRADEV2 came to an end. During 3 years (2023-2025), it provided strong support towards the full implementation of the KM3NeT Research Infrastructure (RI).

The objectives of KM3NeT-INFRADEV2 were multi-fold and divided into dedicated work packages (WPs): prepare a legal entity for the KM3NeT RI (WP2); accelerate the construction of the detector (WP3); develop data management and Open science practices (WP4); and demonstrate KM3NeT as a role-model RI in terms of socio-economic impact and sustainability (WP5).

The work carried out in each WP allowed for the achievement of major milestones for the KM3NeT Collaboration: the creation of the KM3NeT AISBL as the legal entity; the establishment of processes for the safe and efficient construction and operation of the telescope; the implementation of a data environment adapted to pluridisciplinary research and in line with FAIR principles; and the adoption of measures to enhance the socio-economic of KM3NeT and to reduce its environmental impact. All KM3NeT-INFRADEV2 outputs are made public on our website in order to disseminate the results of the project and so they can benefit the scientific community beyond the Collaboration. Moreover, these results will be continuously exploited to ensure the sustainable operation of KM3NeT and strengthen its scientific impact.

The project also provided the Collaboration with additional human and economic resources, allowing in particular for the recruitment of dedicated staff; reminding the constant support of the European Union in favour of KM3NeT, since the beginning of its Design study, in 2006. The end of KM3NeT-INFRADEV2, along with the establishment of the KM3NeT AISBL, also offers KM3NeT a graceful exit of the ESFRI Roadmap (2016-2025) and makes KM3NeT a strong candidate to become an ESFRI landmark.

Thanks to the teams involved for their work towards the full implementation of the KM3NeT RI!

 


KM3NeT Bootcamp brings newcomers together

26th January 2026 – The 2026 KM3NeT Bootcamp was held at the Faculty of Science, in Granada, from January 20th to January 23rd, bringing together newcomers to the collaboration for an intensive introduction to KM3NeT.

Over the course of the bootcamp, the participants explored the structure and organisation of the KM3NeT collaboration, along with the detector design and its technical aspects. The programme combined introductory lectures with hands-on sessions, allowing the attendees to gain practical experience with software and computing tools, calibration procedures, data processing and data quality, simulations.

The agenda also covered key physics topics within the KM3NeT scientific programme, including astronomy, neutrino oscillations, dark-matter searches, and cosmic rays. In addition, the participants were introduced to collaboration duties such as data-taking shifts and outreach activities, underlining the importance of contributing both to KM3NeT operations and to its engagement with the broader community.

Even more than an introductory course, the KM3NeT Bootcamp 2026 served as a welcoming gateway into the collaboration, encouraging participants to actively contribute to the future of the experiment.

We warmly thank the local organizers and the Faculty of Science in Granada for their excellent support in hosting this successful event.

Blazar origin of KM3-230213A?

21 November 2025 – We present a new paper with the title ‘Blazars as a Potential Origin of the KM3-230213A Event‘.

In the paper, we test the hypothesis that the ultra-high-energy neutrino KM3-230213A could come from the diffuse neutrino emission of blazars. Read more

Welcome, ORCA33!

15 October 2025 – A very successful sea operation took place last week, leading to a significant extension of the ORCA submarine telescope. Read more


Search for sterile neutrinos with ORCA6

13 October 2025 – We present a new paper with the title ‘‘Search for an eV-scale sterile neutrino with the first six detection units of KM3NeT/ORCA“.

Sterile neutrinos are hypothetical neutrinos proposed by theoretical physicists to explain unexpected experimental results obtained over the course of the past 25 years. Read more
