The VSiPMT (Vacuum Silicon PhotoMultiplier Tube) is an innovative design we launch for a revolutionary hybrid photon detector. The main idea is to replace the classical dynode chain of a PMT with a SiPM, which therefore acts as an electron detector and amplifier. The aim is to match the large sensitive area of a photocathode with the performances of the SiPM technology. The VSiPMT will have many attractive features and its strongest points are the low power consumption and the excellent photon-counting capability. We proved the feasibility of the idea thanks to an R&D project, started with a Geant4-based simulation study and carried on with an essential experimental activity where we tested the performances of a special non-windowed MPPC by Hamamatsu as electron detector and current amplifier. In this work, we present the results of the full characterization of the first industrial prototypes of VSiPMT.
