• Interaction of radiation with matter
• Scintillators, scintillation and light emission processes (solid, gas and liquid scintillators)
• Photon detectors for UV, visible and IR photons (solid-state) (PIN diodes, APDs, Si-PMTs, G-APDs, CCDs, EBCCDs, EMCCDs etc)
• Detector modelling and simulations II (electric fields, charge transport, multiplication and induction, pulse formation, electron emission, etc)

The MEG experiment searches for the mu(+) -> e(+)gamma decay by stopping on a thin passive target the most intense continuous muon beam in the world. We are studying the possibility to have an active target, which should continuously monitor the muon beam and provide a precise measurement of the decay vertex, complementing the new spectrometer. The detector is based on thin scintillating fibers coupled to silicon photomultipliers (SiPMs), exploiting their insensitivity to the magnetic field, competitive PDE with respect to nominal PMT QE and low HV supply. This device can be used as a stand alone tool. In this paper we present a Monte Carlo simulation for a single fiber coupled to SiPM in order to study the propagation of the photons through the fiber and the response of the SiPM.
