Silicon photo-multipliers, often called "SiPM", are semiconductor photon detectors built from a square matrix of avalanche photo-diodes on common silicon substrate. SiPM have been proposed for several different applications in High Energy Physics, in particular where a large detection granularity and a high photon detection efficiency is needed. In this paper the results of a radiation hardness test performed at the Frascati Neutron Generator are presented. Several SiPMs of different manufacturers have been irradiated integrating up to 7x 1010 1-MeV-equivalent neutrons per cm 2. For the first time, their performance have been recorded during the neutron irradiation and a gradual deterioration of their properties was found to happen already after an integrated dose of the order of 108 1-MeV-equivalent neutrons per cm2. © 2010 by World Scientific Publishing Co.
