Abstract

Over the years, the European Southern Observatory (ESO) and a collaborative network of national agencies, institutes, and universities have continually upgraded the VLT and its array of telescopes, accompanied by various cutting-edge instruments and modules. Among the next generation of instruments, there is CUBES (Cassegrain U-Band Efficient Spectrograph), a mid-resolution spectrograph working in the UV ground-based band (300-400 nm). The work presented here is a proceeding on the CUBES hardware dependability and maintainability analysis up to the successful Preliminary Design Review (passed in December 2022) and some forthcoming updates from the ongoing Final Design phase. The work has been developed during the design phases in order to assess the dependability of the System, as part of the Very Large Telescope, and to verify the compliance with the System requirements. The goal has been the identification of the criticalities and potential failure and the definition of the basics of maintainability in view of the last phases of the project, with the aim to keep the system in operation with high availability. Furthermore, the document provides the functional analysis of the System, with a deep focus on the influence of the “degraded modes” on the reliability of the System. Reliability analysis plays a crucial role in ensuring the components of the CUBES project meet stringent performance expectations. It assesses the likelihood of component failure, providing insights into potential vulnerabilities and enabling proactive problem-solving to enhance overall system reliability.
