Description
IDMAR is a multidisciplinary underwater research infrastructure currently under
construction in the abyssal depths of the Mediterranean Sea, off the
southeastern coast of Sicily. It integrates innovative sensors for real-time
studies in the underwater environment. One of IDMAR’s primary use cases is ARCA,
the Cherenkov detector being developed by the KM3NeT Collaboration as part of
the KM3 Neutrino Telescope, designed to study cosmic neutrinos at TeV-PeV
energies.
A critical component of IDMAR is the Junction Box (JB), which receives electro-
optical signals from onshore via the Main Electro-Optical Cable and distributes
them to underwater experiments, such as the KM3NeT Detection Units (DUs).
The original JB design has been upgraded to support a greater number of DUs,
optimizing costs in the process. Version 2 of the JB design integrates two
independent sub-units within the same mechanical enclosure, each with its own
electro-optical connection. Despite their independence, a unified management
approach ensures operational consistency.
A major advancement in the slow control system is the enhancement of
authentication and authorization mechanisms. In addition to local authentication
via usernames and passwords, the system now supports external authentication
providers. Fine-grained user and group permission management has also been
implemented, improving access control.
This paper presents the key architectural decisions behind these upgrades and
their implementation.
