The DPS mechanism will be exclusively utilized during the alignment and test phase. Upon completing the test phase, it will be mechanically locked at the best pre-determined focus so that it cannot be moved during the observation period. The DPS has been conceptualized as a fixed and reproducible interface to the Main Bench Structure in the MICADO cryostat and as an adjustable unit containing the Detector Array mounted on the DPS frame installed on a linear guide on the base plate. A cryogenic linear actuator further acts as the linear guide during the alignment phase to bring the focal plane array into focus. |
