Description
The goal of KM3NeT ARCA is to search for astrophysical neutrinos with a neutrino telescope operating on the bottom of the Mediterranean Sea, at 3,500 m depth, for more than 15 years. The neutrino telescope is made of Detection Units (DU) each consisting of 18 Digital Optical Modules (DOMs), a Vertical Electro-Optical Cable (VEOC) and a Base Module (BM) whose purpose is to collect the data arriving from the 18 DOMs via the VEOC, pack and transmit them to the on-shore station through a sub-marine infrastructure and to distribute to the DOMs the communications broadcasted from shore. The BM is built with a titanium cylindrical container hosting optics, electronics and power boards. The mechanical requirements placed on it are significant, as it represents a single point of failure for the DU. The main requirements are that it has to be water tight and mechanically resistant to an external water pressure up to 350 bar, it has to be able to stand all mechanical stresses along its life, it has to provide excellent corrosion resistance for 15 years at least in sea water and it has to host all internal components safely, by guaranteeing an adequate heat dissipation. The solutions to solve all such design challenges are here presented. Particular emphasis is given to the tests that have been performed for qualification and to the performance of BMs operating underwater since 2015.
