Studies on Dynamic Range of SiPMs with High Pixel Densities
This study examines the dynamic range and saturation behavior of three SiPM models with pixel pitches of 25 µm, 10 µm, and 6 µm, with respective pixel counts of 57,600, 89,984, and 244,719. Using a picosecond laser as the light source and a photomultiplier tube (PMT) operating at different bias volt...

| Summary: | This study examines the dynamic range and saturation behavior of three SiPM models with pixel pitches of 25 µm, 10 µm, and 6 µm, with respective pixel counts of 57,600, 89,984, and 244,719. Using a picosecond laser as the light source and a photomultiplier tube (PMT) operating at different bias voltages as a scaler, we obtained complete response curves of these devices. The results show that SiPMs with 25 µm and 10 µm pixel pitches reached saturation near their nominal pixel counts, while the 6 µm SiPM saturated at about half its nominal count. |
