520 |a"This work is an experimental investigation of radiation-induced changes in the electrical characteristics of the MRD500 P-I-N photodiode, due to various fluences and energies of neutrons, electrons and gamma-rays. Analyses of changes in MRD500 forward bias current-voltage (I-V) characteristics, as a function of fission spectrum neutron fluence (reported as 1 MeV equivalent), indicate that the device can serve as a neutron fluence monitor, useable well beyond the range of the widely-used Harshaw DN-156 P-I-N diode fluence monitors. Furthermore, experimentally-determined changes in MRD500 forward voltage, ΔVf(ϕ), (at constant If and constant temperature) as a function of various energies and fluences of neutrons, electrons and gamma-rays, demonstrate the potential usefulness of the MRD500 as a displacement damage monitor.In this study, fission neutrons (1 MeV equivalent), 7.5 MeV (average energy) electrons and 1.25 MeV (average energy) gamma-rays are used to investigate the effectiveness of these radiations in producing displacement damage in the MRD500. The device physics responsible for the radiation-induced changes in the electrical characteristics of the diode is also discussed"--Abstract, page iii.
