Description

VSiPMT (Vacuum Silicon PhotoMultiplier Tube) is an innovative hybrid photon detector combining the performances and the potential of SiPM technology with a hemispherical glass PMT standard envelope. Our purpose is to combine the key features of a SiPM (high quantum efficiency, low operation voltages, insensitivity to magnetic fields and robustness) with the large sensitive area of a photocathode. In such a device, the SiPM replaces the standard dynode chain of a PMT, thus acting as an electron multiplier. In order to get a proof of the feasibility of the VSiPMT, we tested the performances of a special non-windowed Hamamatsu MPPC with an electron source. In this work we provide a detailed description of the experimental setup and of our measurements.
