The oversight, governance and management of the implementation and operation of KM3NeT-phase 2 is defined in a Memorandum of Understanding signed by the funding authorities in December 2021.
In 2026 the KM3NeT AISBL has become operational. The top-level structure of the collaboration organisation is now represented by the AISBL Council.
The work of the collaboration is led by a Management Team which is elected by the board of the KM3NeT institutes and is part of the AISBL Executive Board. The Management Team is chaired by the Spokesperson of the collaboration, who is supported by a Deputy Spokesperson, a Technical Project Manager coordinating the construction of the detectors and a Physics and Software Manager for the execution of the science program of the collaboration. The Management Team also includes a site manager for each installation site; the site managers are appointed by the institutes hosting the sites and are responsible for the construction of the subsea and on-shore infrastructures and for the sea campaigns necessary for the deployment of detector components and their connection to the seafloor network.
The management team is supported in its every-day activity by a Technical and a Science Steering Committee, including the coordinators of the technical and scientific subprojects, respectively. The Technical Project Manager leads also a Project Office supporting in management activities. Various committees (Publication Committee, Conference Committee, etc.) are also appointed for carrying out specific tasks.
Engineers and technicians work in the labs of the KM3NeT institutes on the construction and integration of the detector components. Individual scientists usually work in small groups, choosing the research areas and data that interest them most. The scientific output from the collaboration is shared by all members and is subject to rigorous internal review before results are made public.
