Abstract :
In the framework of the LHC project at CERN, the effects of radiation on the electrical characteristics of epitaxial diodes for superconducting magnet protection were studied. The diodes were exposed to an irradiation dose up to 50 kGy and a neutron fluence of 1015 n/cm2 with intermediate thermal annealing each 10 kGy dose steps in the TUM reactor at 4.6 K
