Measurements of efficiency, timing and response to irradiation for direct detection of charged particles with SiPMs
Year: 2026
Type: article
Abstract: In this paper, the efficiency of direct charged particle detection with different silicon photomultiplier (SiPM) sensors has been measured to be close to 100%. A time resolution of about 20 ps has also been confirmed for sensors with an active area of about 3 $$\times$$ × 3 $$\hbox {mm}^{\text {2}}$$ mm 2 and a single-cell pitch of area of 40 $$\times$$ × 40 µ $$\hbox {m}^{\text {2}}$$ m 2 . In addition, the SiPM performance after irradiation, in terms of timing response and dark count rate, has been evaluated for sensors with a 1 $$\times$$ × 1 $$\hbox {mm}^{\text {2}}$$ mm 2 area, demonstrating that SiPMs can maintain excellent timing capabilities and a low dark count rate when an appropriate threshold is applied to the signal.
