Abstract: We analise the efficiency of wavefront reconstruction in the MultiConjugateAdaptive Optics system for the European Solar Telescope EST. We presentpreliminary results derived from numerical simulations. We study a 4 meterclass telescope with multiple deformable mirrors conjugated at variableheights. Along with common issues, difficulties peculiar to the solar case haveto be considered, such as the low contrast and extended nature of the naturalguide features. Our findings identify basic requirements for the EST AdaptiveOptics system and show some of its capabilities.
