Abstract:
The readout of a cheap scintillating fibre was implemented by means of a new solid-state device (Silicon Photomultiplier, SiPM), able to detect very tiny light pulses. The GEANT3.21 code was adopted to simulate the counting detection efficiency and the energy deposited inside the scintillating fibre due to the radiation of a radioactive gamma source. The results obtained show the capability to detect gamma rays producing as few as 3-4 photoelectrons. The new devices may have many applications in radioactivity metrology.
