Abstract

The Main Selection Mechanism (MSM) is the cryogenic mechanism that will allow to switch between the operational modes of MICADO, the first light instruments for the ESO Extremely Large Telescope (ELT). The mechanism, developed by the Universit¨ats-Sternwarte Muenchen (USM), will be located inside the MICADO cryostat and operate under vacuum conditions at cryogenic temperatures. The MSM consists of a main support structure and a rotating platform, where the MICADO Low Resolution Imager, Spectrometer and Pupil Imager modules are located. Manufacturing and procurement activities for the MSM started in late 2022. In this paper we present the current status of manufacturing and procurement for the MSM, and its overall assembly, integration and test (AIT) plan. AIT activities will start end of 2024, and will be concluded with the cryogenic test of the mechanism inside the USM big test cryostat, before the delivery in 2026 of the mechanism to the MICADO lead institute, the Max-Planck-Institute f¨ur Extraterrestrische Physik (MPE), for its final integration inside the instrument cryostat.
