| Summary: | The KM3NeT Collaboration has developed a multi-PMT optical so lution for construction of the two deep-sea ARCA and ORCA telescopes. This approach has several advantages compared to the single-PMT optical modules which have been traditionally used in neutrino telescopes, including a larger photocathode area which is equivalent to three 10-inch photomultipliers. In addition, the multi-PMT approach allows for a high resolution, good positioning and timing calibration. The integration of the optical modules follows a strict protocol and a standardised procedure. It takes place in parallel at eight different integration sites in the labs of the collaboration. In this way, it is possible to reach a significant production rate of more than 100 well-qualified modules per month. In this proceeding, we present details of the technology of the KM3NeT optical module and the integration process. |
