MAORY/MORFEO@ELT: Thermal Control System Preliminary Design
ADAPTIVE OPTICS SYSTEMS VIII(2022)
Abstract
MAORY has undergone the Preliminary Design Review (PDR). The design foreseen for the opto-mechanical work package is based on a light-weighted mirror design with an athermal opto-mechanics to satisfy the requirements in terms of stiffness, mass limit, and thermomechanical loads. In this paper the choices for the following aspects are presented: the mounts working principle, the alignment tools used to reach the operative configuration, the strategy chosen to reach the scientific performance and the preliminary results for the different conditions that the instrument will face @ ELT. Furthermore, a trade off analysis about the different kinds of the possible opto-mechanics in preparation for the Final Design Review is presented.
