Neutron irradiation studies of silicon and liquid phase epitaxial (LPE) GaAs Schottky barrier radiation detectors were carried out using 1.1 MeV fast neutrons produced using the Australian Nuclear Science and Technology Organisation's 3 MeV Van de Graaff accelerator. Neutrons were provided by bombardment of a 7Li target with 3 MeV protons to a maximum fluence of 7 × 1013 neutrons cm-2. Neutron damage to the detectors was characterised using capacitive deep level transient spectroscopy, optical deep level transient conductance spectroscopy, current-voltage measurements and capacitance-voltage measurements. The degradation of 241Am spectra was also observed.
