MOSAIC on the ELT: Front-End and instrument AITV planification

MOSAIC is the Multi-Object Spectrograph for the ESO-ELT (European Southern Observatory-Extremely Large Telescope). The Laboratoire d'Astrophysique de Marseille (LAM) is in charge of the “Assembly, Integration, Test and Verification (AIT/V)” activities for both the Front-End channel level and the instrument level in Europe (LAM) and at the Telescope. AITV for AO instruments, in laboratory as well as at the telescope, always represent numerous technical challenges. We already started the preparation and planning for the Front-End and instrument AIT activities, from identification of needs, challenges, risks, to defining the optimal AIT strategy. In this paper, we present the state of this study and describe the MOSAIC AITV organization, give an overview of the Front-End and the Instrument MAIT flows. We also describe the visible and near-infrared channels MAIT flows as well as the different AITV responsibilities during the AITV phases both in Europe and in Chile.
