LHC power diodes irradiated at 77 K in the field of a high energy accelerator

In the framework of the LHC research at CERN, the silicon power diodes used for superconducting magnet protection must be tested in radiative environment such as high energy particle accelerator. Diode samples have been irradiated at 77 K, near a conversion target in the TCC2 area of the SPS at CERN. using a mixed irradiation (gamma rays and neutrons).
