Abstract

The Multi-Adaptive Optics Imaging Camera for Deep Observations is one of the first light ESO Extremely-Large-Telescope (ELT) Instruments and now in it's final design stage. At a previous SPIE we sketched the PLC-based instrument control system, now we highlight more specific issues like efforts on thermal management system optimization, improvements on harness properties and advantageous controller conceptions - all seen in the context of ESOs requirements. We focus now on details for the 9 motorized cryogenic axis as well as the cryogenic and vacuum control and supervision for the delicate cryostat opto-mechanical and detector components embedded into ESO`s instrument control system environment.
