Characterization of telecentric dual-etalon Fabry-Pérot systems from observational data. Properties of the CRISP2 instrument at the Swedish 1-m Solar Telescope
J. de la Cruz RodrÃguez, G. B. Scharmer, P. Sütterlin +5
Imaging Fabry-Pérot Interferometer (FPI) observations are commonly used in solar physics to infer physical parameters in the photosphere and chromosphere through modeling of the o…
Operating the Fabry-Pérot systems of the European Solar Telescope in multi-aperture mode
G. B. Scharmer, M. G. Löfdahl, J. de la Cruz RodrÃguez +5
We discuss how to optimise the science output of the European Solar Telescope (EST), when used without the wide-field compensation for high-altitude seeing that the EST multi conju…
The making of robust and highly performing imaging spectropolarimeters for large solar telescopes
G. B. Scharmer, J. de la Cruz RodrÃguez, J. Leenaarts +7
We discuss the requirements, concepts, simulations, implementation, and calibration of two dual Fabry-Perot based imaging spectropolarimeters, CRISP and CHROMIS, at the Swedish 1-m…
High flow speeds and transition-region like temperatures in the solar chromosphere during flux emergence
J. Leenaarts, M. van Noort, J. de la Cruz RodrÃguez +7
Context: Flux emergence in the solar atmosphere is a complex process that causes a release of magnetic energy as heat and acceleration of solar plasma at a variety of spatial scale…
