Recent developments regarding the European Solar Telescope design and science capabilities

The optical design of EST has been updated to include an Adaptive Secondary Mirror that becomes part of the Multi-Conjugated Adaptive Optics (MCAO) system. This new concept allows simplifying the optical design reducing the number of optical surfaces before the instrument suite. The project has also announced a call for tenders for the Preliminary Design of three main systems: the primary mirror assembly, the telescope structure, pier and enclosure, and the adaptive secondary mirror. In terms of science capabilities, the Science Advisory Group (SAG) published an updated version of the Science Requirements Document in December 2019. The EST Project Office elaborated a database of instrument requirements based on that document. After discussing it with the newly formed EST Review Panel, we developed a tentative light distribution and instrument suite diagram. It was presented and approved by the SAG in June 2020. We are now starting to create the instrument developers teams to achieve the proposed performance. Our goal is to deliver the community the full construction proposal of the telescope and the instruments by the end of 2022.
