Abstract

The performances of the ARAPUCA depends on the efficiency of the photosensitive device, of the shifters+dichroic filter system and on the collection efficiency of the passive box. The latter needs to be maximized by optimizing the geometry of the box and choosing the best reflector (diffusive or specular). (AU)
