Abstract

Nuclear quadrupole resonance is one of the express and highly informative methods of experimental research and has a number of practical applications, in particular for pulse detection of explosive and narcotic substances in non-metallic containers, which include the 14N isotope. One of the key problems of equipment of this class is the need to use a specific radio frequency transmitter, which must correspond to the given signal and energy characteristics. The paper proposes an applied solution for the operating layout of such a device for a pulsed Fourier spectrometer of nuclear quadrupole resonance and considers the key aspects of battery power supply. Experimental studies have confirmed that the device provides amplification of excitation signals up to 1.2 kW in the frequency range 100 kHz - 10 MHz and up to 1.7 kW at the resonant frequency 14N - 4.65 MHz.
