Study of RF Coil in NQR Explosive Detection System

摘要：

　　The modules of nuclear quadrupole resonance (NQR) explosive detection system are introduced,and the key component—radiofrequency (RF) coil—is researched.In this paper,the small-sized solenoid coils diameter,length and number of turns are defined.Experimental tests show that this coil has large signal-to-noise ratio (SNR) and high sensitivity.It can detect the NQR signal quickly and accurately,proving the feasibility of coils design theory and manufacturing method.The design method is very important for the improvement of the accuracy of hidden explosives detection and the design of the RF coil under different experimental conditions.
