A New-Type Silicon Photomultiplier with Wide Dynamic Range for Effective Detecting of Short Light Pulses in Analog Mode

The new-type silicon photomultiplier with high density of cells (HD-SiPM) was developed by DEPHAN for the task of analog detecting of short light pulses. In this work we have tested and compared with known references its responsivity, amplitude and time resolution by short laser pulses (442 nm) in a wide range of signal intensities. The results demonstrate, that the new detector could be interesting for Hi-Res Medical Imaging and other pulse detecting applications in nuclear science, especially those requiring combination of sensitivity, high speed and dynamic range from a small-area detector or an array element.
