The European Solar Telescope (EST) aims to become the most ambitious ground-based
solar telescope in Europe. Its roots lie in the knowledge and expertise gained from building …

Abstract European Solar Telescope (EST) represents the largest European research
infrastructure projected in the field of solar astrophysics. It is a 4-meter class solar telescope …

This paper describes the preliminary design of the Adaptive Secondary Mirror (ASM) for the
European Solar Telescope (EST), as designed by TNO. This ASM will contain 1950 …

The European Solar Telescope (EST) is a 4.2-metre telescope that will be equipped with a
multi-conjugate adaptive optics (MCAO) system to provide a high spatial resolution over a …

This contribution presents the structural analysis that followed the preliminary design
specifications of the European Solar Telescope (EST). EST is a 4-metre class telescope …

Modern astronomical polarimeters often require simultaneous operation of multiple
instruments over broad wavelength ranges. The 4 m DKIST solar telescope will soon cover …

Abstract The 2.5 m wide-field and high-resolution solar telescope (WeHoST) is currently
under developing for solar observations. WeHoST aims to achieve high-resolution …

Phase Diversity (PD) is a technique widely used to measure and compensate for Non-
Common Path Aberrations (NCPA) in optical systems. Beyond its traditional applications, PD …

The European Solar Telescope (EST) is a 4-m class solar telescope that will include a multi-
conjugate adaptive optics system (MCAO) integrated in the telescope optical path. Currently …

The temperature distribution and the difference with the ambient temperature of the primary
mirror are crucial factors affecting the observational quality of the solar telescope. We …
