SiPM Linearity Measurements. Measurement of the SiPM response to a laser (430 nm) SiPM readout with preamps designed for IC APDs (last amplification stage was bypassed to reduce gain) Single photo electrons peaks clearly visible (spe~12 mV) System linearity checked up to 120 PE

SiPM Linearity Measurements • Measurement of the SiPM response to a laser (430 nm) • SiPM readout with preamps designed for IC APDs (last amplification stage was bypassed to reduce gain) • Single photo electrons peaks clearly visible (spe~12 mV) • System linearity checked up to 120 PE • Preamp gain still too high for the foreseen dynamical range (~1000 PE) Measurements by A.
