The VIRHIS spectrometer is part of the ESA mission JUICE on Jupiter moons Callisto, Europa and Ganymede. The dichroic filters are ZnS and ZnSe, for each of them we have three different sample named L, S and T. Only the sample S was subjected to the radiation test. After a previous test campaign at ambient temperature on the dichroics, the test were performed at the facility DAFNE – BTF in Rome on 16-22 Jenuary, 5-11 March 2012, 9-15 July and 24- 30 September.ELETTRONICOenResearch 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
