| Abstract Scope |
This study characterizes the response of pre-existing nitrogen-vacancy (NV) centers in diamond to neutron irradiation conducted at The Ohio State University's 500-kW research reactor, followed by thermal annealing at 900 °C for several hours. Diamonds containing a known concentration of NV centers undergo controlled neutron exposure to investigate the relationship between 1-MeV neutron fluence and the degradation of existing NV populations. Post-irradiation annealing promotes vacancy mobility, enabling recombination and potential defect restructuring. Optically Detected Magnetic Resonance (ODMR), integrated with confocal microscopy, provides spatially resolved quantification of NV center densities before and after irradiation. The depletion of NV centers and their correlation with neutron fluence could enable quantum sensing applications in reactor environments and radiation monitoring. |
