In this paper we report on the characterization of SiPM tiles developed for the R&D on the DUNE Photon Detection System. The tiles were produced by Fondazione Bruno Kessler (FBK) employing Near Ultra-Violet High Density Standard Field (NUV-HD-SF) SiPMs. Special emphasis is given on cryo-reliability of the sensors, i.e. the stability of electric and mechanical properties after thermal cycles at room and 77 K temperature. The characterization includes the determination of the I-V curve, a high sensitivity measurement of Dark Count Rate at different overvoltages, and correlated noise. The single p.e. sensitivity is measured as a function of the number of sensors connected to a single electronic channel, after amplification at 77 K using a dedicated cold amplifier.

Abstract
In this paper we report on the characterization of SiPM tiles developed for the R&D on the DUNE Photon Detection System. The tiles were produced by Fondazione Bruno Kessler (FBK) employing Near Ultra-Violet High Density Standard Field (NUV-HD-SF) SiPMs. Special emphasis is given on cryo-reliability of the sensors, i.e. the stability of electric and mechanical properties after thermal cycles at room and 77 K temperature. The characterization includes the determination of the I-V curve, a high sensitivity measurement of Dark Count Rate at different overvoltages, and correlated noise. The single p.e. sensitivity is measured as a function of the number of sensors connected to a single electronic channel, after amplification at 77 K using a dedicated cold amplifier.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
