IBIS 2.0: Interferometric Bidimensional Spectrometer 2.0 at the THEMIS solar telescope

Le résumé fourni par la source

The IBIS2.0 project aims to upgrade the Interferometric BIdimensional Spectrometer, originally operated at the Dunn Solar Telescope of the National Solar Observatory from 2003 to 2019, for its relocation and installation at the THEMIS solar telescope at the Teide Observatory. The refurbished instrument integrates the original dual Fabry-Perrot etalons with a new polarimetric unit, interference filters, new scientific cameras, and a fully modernised instrument control and data-handling system. These upgrades to the scientific sensors and the control system have enabled us to automate the instrument's operations. IBIS2.0 is designed to preserve the spectral coverage of the original system (580-860 nm) while offering enhanced stability and robustness. The integration (Hardware and Software) of the instrument at THEMIS is currently underway. In this contribution, we present the installation progress at the new telescope as well as the new observational capabilities that it will offer.
