A Look at the New Technologies for the Solar Telescopes of the Future
A critical source of image degradation in solar telescopes is the heat concentrated at the primary focus (F1) in between primary mirror and secondary mirror. In F1 all the solar radiation collected by the primary mirror is concentrated in a very small area and heating processes leads to internal turbulence. A Heat Rejecter based on innovative heat removing method is designed and realized. Next generation telescopes will need Fabry-Pérot interferometers digitally controlled to acquire high resolution images of our star. The solar and space physics team of the Department of Physics present the prototypes of the heat rejecter and Fabry-Pérot digital controller for the future 4-m class European Solar Telescope
Luca Giovannelli, Francesco Berrilli, Dario Del Moro
Francesco Berrilli is professor of Computational Physics and Solar and Space Physics at the Department of Physics at the University of Rome Tor Vergata and member of "Accademia dei Lincei". He began his astrophysical career at Institute of Plasma Physics-CNR working in the field of infrared astronomy and star formation. From 1990 he is experimental solar astrophysicist and was involved in the acquisition systems and data calibration pipeline for Arcetri Tower in Florence, THEMIS-IPM (Tenerife, Spain) and DST-IBIS (NM, USA). He is involved in various WPs of the European Solar Telescope project (Heat Stop, Large Etalon, FPI digital controller,..). He has been Principal Investigator of the ADAHELI project for an Italian solar satellite and involved in various MOF-based telescopes, included the South Pole Solar Observatory (SPSO). Scientific topics of interest concern: solar activity, turbulent convection in the photosphere, Sun-Earth connection, sun-like stars, Space Weather
