Abstract: (Springer)
Considering the R&D for upgrading the and detectors in the Belle II experiment using a scintillator and silicon photomultiplier (SiPM), we designed a compact high-speed and low-noise preamplifier. The preamplifier demonstrated a good gain stability, bandwidth of , baseline noise level of , dynamic range of up to of the input signal amplitude, good time resolution of , and it can be comprehensively applied to SiPMs. Adopting pole-zero-cancelation in the preamplifier reduces both the rise and fall times of the SiPM signal, which can significantly improve the time resolution and reduce the pile-up when using a large SiPM or an array of SiPMs. Various combinations of the preamplifier and several types of SiPMs demonstrated time resolutions better than for most cases; when the number of detected photons was larger than 60, a time resolution of approximately was achieved.- Silicon photomultiplier
