Atmospheric neutrino flux measured with ORCA6
15 July 2025 – The European Physical Journal C has accepted for publication a new KM3NeT paper with the title ‘Measurement of the atmospheric νμ flux with six detection units of KM3NeT/ORCA‘.
KM3NeT - KM3NeT
KM3NeT AISBL is born!
20 June 2025 – A very important step forward for KM3NeT has been accomplished this week by establishing the KM3NeT AISBL!
The Online Data Filter for the KM3NeT Neutrino Telescopes
10 June 2025 – Recently, we submitted a new paper with the title ‘The Online Data Filter for the KM3NeT Neutrino Telescopes’
In this paper, we present the design and performance of the software that is used to filter the data recorded by the photo-sensors of the KM3NeT detectors.
2nd DOM integration workshop
27 May 2025 – Do you know how the optical modules of KM3NeT are built? This has been shown and practised in the second edition of the Digital Optical Module (DOM) integration workshop which took place last week.
4 new detection units installed in ORCA
16 May 2025 – This week at the ORCA site, a sea operation was performed with a twofold purpose: the recovery from the sea bottom of some oceanographic instruments which required some maintenance and the installation of a set of 4 new detection units. The number of detection units in ORCA has thus been increased to 28.
Inauguration of the new facilities of the CAPACITY Laboratory in Caserta
14 May 2025 – Today the new facilities of the CAPACITY laboratory in Caserta have been inaugurated.
Observation of an ultra-high-energy cosmic neutrino with KM3NeT

Tau neutrinos and neutrino mixing with ORCA6
6 February 2025 – We present a new paper with the title ‘A study of tau neutrinos and non-unitary neutrino mixing with the first six detection units of KM3NeT/ORCA‘.
A fruitful Collaboration Meeting in Louvain-la-Neuve!
4 February 2025 – Last week, KM3NeT has met, both in person and online, for its winter Collaboration Meeting , in Louvain-la-Neuve, Belgium, hosted by UCLouvain.
Sneak peek into the KM3NeT labs: Nikhef
17 January 2025 – Today we start a series of items highlighting the work of our technical staff in the labs of KM3NeT. Numerous technicians and engineers are working on the construction of the ARCA and ORCA detectors of the KM3NeT neutrino telescope. Together, but in distributed labs, they design and build the many detector components, assemble them into thousands of optical modules and integrate them into hundreds of deployment-ready detection units. It requires high standards of quality control and logistics between the labs.
