The dichroic shall withstands the Jupiter and the icy moons electron radiation environment without any permanent degradation at the end of the mission. To verify the effect of the electron flux on the optical performances of the dichroic, transmittance and reflectance measurements have been repeated after each irradiation test performed.ELETTRONICOenTechnical reportFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation::PE9_2 Planetary systems sciences
