Abstract
Micro-electro-mechanical systems (MEMS) have been previously shown to be a viable option for radiation sensors requiring small, low-cost, and low-power designs. A resistive sensor combining boron-nitride nanotubes and multi-walled carbon nanotubes with an interdigitated electrode design printed with conducting ink can be used to detect thermal neutron radiation. This thesis explores how the initial resistance of the boron-nitride nanotube and multi-walled carbon nanotube mixture, which forms the connections across the printed conductive ink, influences the percent change in resistance of the sensor after thermal neutron exposure. The experiments will determine an ideal initial resistance that will produce the most sensitive resistor with ideal dynamic range. A key aspect of this research proved that the results of a resistor showing increasing resistance with neutron exposure are reproducible by comparing the results to work performed previously by the Naval Postgraduate School.
