DESCRIPTION:Speakers: paolo walter cattaneo (INFN Pavia)\nRadiation hardne
 ss is an important requirement for solid state readout elements operating 
 in high radiation environments common in particle physics experiments. The
  MEG II experiment at PSI\, Switzerland\, investigates the forbidden decay
  μ+ → e+ γ. exploiting the most intense muon beam of the world. A sign
 ificant flux of non-thermal neutrons (kinetic energy Ek ≥ 0.5 MeV) is p
 resent in the experimental hall produced along the beamline and in the hal
 l itself. \nWe present the effects of neutron fluences comparable to the M
 EG2 expected doses on several Silicon PhotoMulitipliers (SiPMs). The teste
 d models are: AdvanSiD ASD-NUV3S-P (the same model used in MEG II)\, Advan
 SiD  ASD-RGB3S-P\, Hamamtsu s12571-050P and  Excelitas C30742-33-050-x.\nT
 he neutron source is the thermal Sub-critical Multiplication complex (SM1)
  moderated with water\, located at the Department of Chemistry University 
 of Pavia (Italy).\nWe report the change of SiPMs most important electric p
 arameters: dark current\, dark pulse frequency\,  gain\, direct bias resis
 tance\, as a function of the integrated neutron fluence.\n\nhttps://indico
