Description

Imaging sensors made from an ionization target layer of amorphous selenium (aSe) coupled to a silicon complementary metal-oxide-semiconductor (CMOS) active pixel array for charge readout are a promising technology for neutrino physics. The high spatial resolution in a solid-state target provides unparalleled rejection of backgrounds from natural radioactivity in the search for neutrinoless ββ decay and for solar neutrino spectroscopy with 82Se. We present results from the first aSe/CMOS devices optimized for charge collection in aSe. We explore the scientific reach of a large neutrino detector with the proposed technology based on our experimental understanding of the detector performance.
