Description
VSiPMT (Vacuum Silicon PhotoMultiplier Tube) is an innovative hybrid photon detector suggested by our group in order to combine the performances and the potential of PPD technology with a hemispherical glass PMT standard envelope. Our purpose is to combine the key features of a PPD (high quantum efficiency, low operation voltages, insensitivity to magnetic fields and robustness) with the large sensitive area of a photocathode. The PPD therefore acts as an electron detector. In order to study the performances of the PPD in such a configuration we carried out a preliminary work going from the characterization of a special non-windowed Hamamatsu MPPC with a pulsed laser source to the realization of a Geant4-based simulation of the interaction between the PPD and an electron beam. The last step consists in the characterization of the PPD with an electron source. In this work we will provide a detailed description of the experimental setup and of our preliminary measurements.
