Abstract Accurate characterization of quantum yield is crucial to the reconstruction energy depositions in silicon at eV scale. This work presents a new method for experimentally calculating using vacuum UV-sensitive photomultipliers (SiPMs), which can be used determine probabilities that UV photon absorbed crystal will produce one, two, or three electron–hole pairs. Results are presented fully constrain distribution energies up 7.75 eV. works by exploiting saturation detection efficiency...
Presents corrections to the paper, Corrections "Stimulated Secondary Emission of Single-Photon Avalanche Diodes".
In this paper, we report on the photon emission of Silicon Photomultipliers (SiPMs) from avalanche pulses generated in dark conditions, with main objective better understanding associated systematics for next-generation, large area, SiPM-based physics experiments. A new apparatus spectral and imaging analysis was developed at TRIUMF used to measure light emitted by two SiPMs considered as photo-sensor candidates nEXO neutrinoless double-beta decay experiment: one Fondazione Bruno Kessler...
Large-area next-generation physics experiments rely on using Silicon Photo-Multiplier (SiPM) devices to detect single photons, which trigger charge avalanches. The noise mechanism of external cross-talk occurs when secondary photons produced during a avalanche escape from an SiPM and other within detector system. This work presents measured spectra the emitted Hamamatsu VUV4 Fondazione Bruno Kessler VUV-HD3 SiPMs stimulated by laser light, near operational voltages. describes Microscope for...

A byproduct of the detection mechanism used in silicon photo multipliers are secondary photons. These photons degrade performance SiPMs through internal optical cross-talk, and detector systems external cross-talk. In this work we examine spectral distribution produced during avalanche four devices their impact on large area photodetection systems.
Abstract We study a possible calibration technique for the nEXO experiment using 127 Xe electron capture source. is next-generation search neutrinoless double beta decay (0 νββ ) that will use 5-tonne, monolithic liquid xenon time projection chamber (TPC). The xenon, used both as source and detection medium, be enriched to 90% in 136 Xe. To optimize event reconstruction energy resolution, calibrations are needed map position- time-dependent detector response. 36.3 day half-life of its small...
We demonstrate the use of simulations in modeling and characterization important aspects Single Photon Avalanche Detectors (SPADs). Electrically, we discuss drift-diffusion avalanche triggering probability solvers results for dark count rate (DCR) their comparison to measurements. Optically, full wave electromagnetic simulate transmission function secondary emission photons that cause crosstalk. Combined with optical measurements, how calculate photon production spectrum.
