Description
The feasibility of developing an optically-based sensing system that is capable of noninvasively characterizing pulsed magnetic fields with single-millimeter spatial resolution either inside or external to a cavity exposed to x-ray or gamma radiation will be investigated. An optical-fiber-coupled sensor will be designed, fabricated, and experimentally verified to meet or exceed desired sensitivity, bandwidth, and rise-time specifications while resolving real-time, single-event magnetic-field transients. A theoretical investigation of the effects of x-ray and/or gamma-ray exposure on the optical sensor components will be conducted, and experimental identification will be made of any disruption to the probe-measurement capability during and/or after exposure to appropriate ionizing-photon energies and dosages. A novel time-domain calibration algorithm will be developed and applied to experimentally extracted magnetic-field pulses in order to optimize the magnitude and pulse-shape accuracy.
