MICADO is the ELT first light instrument, an imager working at the diffraction limit of the telescope thanks to two adaptive optics (AO) modes: a single conjugate one (SCAO), available at the instrument first light and developed by the MICADO consortium, and a multi conjugate one (MCAO), developed by the MORFEO consortium. Although the project final design review process is about to be completed, the review board and ESO acknowledged that "the review of the final design can be considered complete for the majority of the MICADO sub-systems" and agreed that MICADO can start manufacturing. For the MICADO SCAO module, we have started the manufacturing of several parts: the majority of the SCAO optics and of the SCAO mechanics, the real-time computer software and the instrument control software. This manufacturing is ordered in several steps to allow the progressive integration of a first full AO close loop with the final SCAO parts. In this contribution, we will focus on the first two steps: on our AO Sésame bench and the so-called "β flat configuration". We will present the status of this manufacturing and the first results obtained.
On-sky testing is a key step in taking an instrumentation concept from the laboratory to deployment within a facility-class instrument. Access to dedicated test facilities can help reduce the cost and time associated with this process, particularly concepts that rely on the use of Adaptive Optics. The H2020 OPTICON-RadioNet Pilot (ORP) program is funding access time specifically for testing new visitor instrument concepts using the facilities developed for CANARY and LGS AO experiments. Here we provide further details of the facilities and support that is being offered and give details of the call for proposals for visiting experiments for 2023.
