In this paper we present the status of the Thermal Control System (ThCS) with a focus on the thermal and cooling circuits design. The prototyping plan foreseen for the future to validate this circuit is also presented.
The design and analysis of the steel bench is presented together with the design, analysis, and prototyping of the optomechanical elements. Particular attention is given to the evolution of the derotation system design (K-mirror), which has been strongly improved, and to the prototyping plan.
MORFEO (formerly known as MAORY) is an adaptive optics module able to compensate the wavefront disturbances affective the scientific observation. It will be installed on the straight-through port of the telescope Nasmyth platform to serve the first-light instrument MICADO and with the provision for a future second instrument. The module underwent the Preliminary Design Review in 2021 and is expected to be commissioned in 2029.
In this paper we present the current status of the Thermal Control System (ThCS) including the modifications required during the Preliminary Design Review. Due to the peculiar optical and mechanical design, a number of FEM and CFD analysis have been performed to verify the compliance of the system to the technical budget. The results of those analysis are then showed together with the current thermal and cooling circuits design derived from them.
