Silicon Photomultipliers (SiPM) are a new class of photon sensors featuring single photon detection sensitivity, high photon detection efficiency, low excess noise factor, extended dynamic range and magnetic field immunity. Operated at voltages not exceeding 100 V with a power consumption lower than 100 mW, SiPM benefit from the tremendous development of the Silicon technology in terms of cost production, design flexibility and performances.

They have been proven to be suitable for an increasing number of applications in science and industry and they are bound to open new perspectives in low light detection systems. This is the main reason why, few years ago, an R&D program was started in collaboration with CAEN S.p.A. to design a modular set-up that allows to easily operate SiPMs from different producers. The system, together with a dedicated simulation of the sensor response, is meant to be the base for the device characterization and the proof of concepts for new SiPM-based applications.

The main characteristics of the system will be presented together with a series of exemplary applications in medical dosimetry and homeland security, within projects funded by the European Commission with the Frameworks programs 6 and 7.
