Abstract
The aim of this thesis is to present the structural design of the ‘Enclosure’ for the Multi-conjugate Adaptive Optics RelaY (MAORY) for the Extremely Large Telescope. MAORY will enable high-angular resolution observations in the near infrared by employing real-time compensation of the wavefront distortions due to atmospheric turbulence. The study was developed at INAF – Astronomical Observatory of Capodimonte (Naples) in collaboration with the University of Naples Federico II. The main purpose of the Enclosure is to protect the optomechanical elements and to achieve a uniform temperature distribution in its internal environment. The mechanical design of the Enclosure was done, using a 3D CAD software, matched by a set of structural FE analyses, to verify the design compliance with ESO (European Southern Observatory) requirements. Moreover a study was carried out to thermally characterize a single panel of the Enclosure, in order to achieve better thermal stability of the system and thus high image quality.
