proton/neutron damages contribute similarly to leakage current increase The damage constant (slope) ~ consistent with n-bulk damage constant (  ~ 4 x10 -17 A/cm) The leakage current of non- irradiated p-bulk sensors is at the similar level to HPK n-bulk sensors V FD ~700V  = 10 15 cm -2 Current/ V =    Leakage Current (@500/800V) with protons Agreement between sites (Tsukuba/KEK and Liverpool) K.
