“…Measuring two Quads at the same time decreases the length of time required for the measurement campaign, but two Quads facing each other introduces an additional source of noise in the form of external cross-talk. External cross-talk is a source of CA caused by the emission of photons from another SiPM detected in the test SiPM [14], which will impact the measurements as a fictitious increase in the DCR and additional CAs. A 14-mm-thick block of HDPE was installed between the Quads to block the external cross-talk photons.…”

The Scintillating Bubble Chamber (SBC) collaboration purchased 32 Hamamatsu VUV4 silicon photomultipliers (SiPMs) for use in SBC-LAr10, a bubble chamber containing 10 kg of liquid argon. A dark-count characterization technique, which avoids the use of a single-photon source, was used at two temperatures to measure the VUV4 SiPMs breakdown voltage (VBD), the SiPM gain (g SiPM), the rate of change of g SiPM with respect to voltage (m), the dark count rate (DCR), and the probability of a correlated avalanche (PCA) as well as the temperature coefficients of these parameters. A Peltier-based chilled vacuum chamber was developed at Queen's University to cool down the Quads to 233.15 ± 0.2 K and 255.15 ± 0.2 K with average stability of ±20 mK. An analysis framework was developed to estimate VBD to tens of mV precision and DCR close to Poissonian error. The temperature dependence of VBD was found to be 56 ± 2 mV K-1, and m on average across all Quads was found to be (459 ± 3(stat.)±23(sys.))× 103 e- PE-1 V-1. The average DCR temperature coefficient was estimated to be 0.099 ± 0.008 K-1 corresponding to a reduction factor of 7 for every 20 K drop in temperature. The average temperature dependence of PCA was estimated to be 4000 ± 1000 ppm K-1. PCA estimated from the average across all SiPMs is a better estimator than the PCA calculated from individual SiPMs, for all of the other parameters, the opposite is true. All the estimated parameters were measured to the precision required for SBC-LAr10, and the Quads will be used in conditions to optimize the signal-to-noise ratio.

“…Unlike time-uncorrelated thermal dark pulses, these burst of pulses are time-correlated to an initial signal pulse. Although the rate of these burst events is very low, it may increase the external cross-talk [9] and may impact on the physics results of some dedicated rare dark matter and neutrino physics event searches and may weakens the energy resolution of the detectors.…”

Studies of event burst phenomenon with SiPMs in liquid nitrogen

Silicon photomultiplier (SiPM) are used to collect scintillation photons in many cryogenic noble liquid detectors deployed around the world, such as DarkSide, nEXO, MEGII, ProtoDUNE and DUNE. An event burst phenomenon was observed during routine characterization on many models of SiPMs operated in liquid nitrogen. These bursts of consecutive pulses are initiated by an intense dark photoelectron pulse with an event rate much lower than the time-uncorrelated thermal dark pulse. Although the rate of these burst events is very low, it can potentially compromise some dedicated rare physics event searches which are also anticipated to be of extremely low rate. Here, we systematically studied the behavior of the event burst phenomenon and identified the probable cause of the phenomenon. This investigation is important for the selection of SiPMs for use in noble liquid detectors, high energy physics experiments, and industrial applications where SiPMs are used in cryogenic environment.
