| dcterms.abstract | Silicon Photomultipliers (SiPMs) are devices capable of achieving the single photon resolution required over the large area $(4 \ m^2)$ required for the next Enriched Xenon Observatory (nEXO) experiment. In addition, SiPMs function with lower noise at cryogenic temperatures in the range that will be used in the full scale experiment, demonstrating a significant drop in the noise of the sensor. nEXO requires a large photosensitive area inside the time projection chamber (TPC) due to the increased mass of Xenon expected when compared with the previous EXO experiment. Practically implementing a photosensitive area of this scale requires consolidation of multiple SiPMs into fewer readout channels in order to minimize power draw and required electrical connections of the SiPM readout system while maintaining an acceptable photon resolution. SiPMs were procured to study the photon counting resolution achievable with various connection schemes (series, parallel, or a hybrid of the two) in order to reduce the number of required electronic readout channels. A test setup was assembled in which pulsed light of a controllable frequency and flux were incident on a fixture holding one or multiple SiPMs. Experimental data showed that the series configuration of SiPMs is able to measure the incoming light down to the single photon level. The gain of the series SiPM array agreed with theoretical predictions, although biasing resistors were required to obtain a resolution acceptable for the nEXO experiment. | |
