Oscillograph capture and the photon number resolution spectra of the SiPMs employed in this work. (a) Oscillograph showing the avalanche pulses from the FBK SiPM (model = NUV-HD-LF) under the irradiation of the focal spot; (b) Photon number resolution (histogram of the waveform area) spectrum of the FBK SiPM; (c) Waveforms of the avalanche pulses from the NDL SiPM (model = EQR1011-1010C-T) under the irradiation of the focal spot; (d) Photon number resolution spectrum of the NDL SiPM; (e) Oscillograph showing the avalanche pulses from the Hamamatsu SiPM (model = S12571-010C) under the irradiation of the focal spot; (f) Photon number resolution spectrum of the Hamamatsu SiPM.
