Locating Materials with Nuclear Quadrupole Moments within Surface Coil Array Area
Abstract
This paper focuses on detecting solid state materials that have a nuclear quadrupole moment using surface coil arrays. With surface coils in the array decoupled from one another, the location and dimension of the material can determined based on the nuclear quadrupole resonance (NQR) signal strength from the surface coil in the array. Experimental investigations will be used with two 7 a diameter, single turn, surface coils overlapping for decoupling, and tuned to detect the unique 28.1MHz NQR frequency from potassium chlorate (PC) sample at room temperature. The PC sample will be in different locations parallel to the surface plane of two tuned coils at a A1/2a standoff distance perpendicular to the surface area. PC location predictions are made with a quadrant surface coil array using the experimental results from the dual surface coil array.
