Design of the Radio Frequency Coil in a Nuclear Quadrupole Resonance(NQR)Explosive Detection System

Hao Feng-lon

Abstract

The radio frequency(RF)coil is a key component in the nuclear quadrupole resonance(NQR)explosive detection system to pick up the signals.In this study,we aimed to optimize the design of small-sized solenoid coils for NQR explosive detection,including the diameter,length and number of turns of the coil.Experimental tests showed that the optimized coil had high sensitivity,and could be used to detect the NQR signals of explosives quickly and accurately.
