Abstract

The most critical components of the X-ARAPUCA for its correct operation are the optical components: the dichroic filter, the waveshifting plate and the reflectors. These components for the PhotonDetection system of the DUNE experiment are under the responsibility of the UNICAMP group. The IC candidate will participate to the test andvalidation procedure of the optical components in a Vacuum UltraViolet Monochromator installed in the Laboratorio de Leptons of IFGW.
