Abstract :
The behaviour of some isolation amplifiers irradiated at the CERN PSAIF facility is described. These components were irradiated to total integrated neutron fluences varying from 1.2×1013 n/cm 2 (E>140 keV) to 1.34×1014 n/cm2 (E>140 keV). The degradation of the electrical characteristics was measured versus doses. These amplifiers could be used for the superconducting magnet protection of LHC. They will be placed inside the tunnel and they will be exposed to 2.5×1013 n/cm2 (E>140 keV) during 10 year operation life time
