NUCLEAR QUADRUPOLE RESONANCE SIGNAL DETECTION DEVICE Russian patent published in 2019 - IPC G01N24/08 

FIELD: nuclear physics.

SUBSTANCE: use: for detecting nuclear quadrupole resonance signals. Summary of invention consists in the fact that in system for detecting nuclear quadrupole resonance signals, which includes a sweep frequency generator, a power amplifier and a matching device, further includes a frequency pulse former, a time pulse generator, a multi-frequency in-phase receive antenna system, multifrequency in-phase transmitting antenna system, information receiving system shaper, filter unit, nuclear quadrupole radiation resonance spectrum analyzing unit, radiation nuclear quadrupole resonance spectrum processing unit, wherein the output of the oscillating frequency generator is connected to the power amplifier input in parallel through the frequency pulses generator, through the first switch Sw. 1, as well as through the time pulses generator, through second switch Sw. 2; output of power amplifier is connected in parallel to input of matching device of transmitting system and through "n₁" Input with receiving system information generator; "n" outputs of matching device of transmitting system are connected to each of "n" in system of emitters 7 through terminal "zh", starting from 7₁ up to 7_N; "n" inputs of the information receiving system information former are connected to N inphase lines 6, for example, "n" inputs of the information former are connected to the first in-phase receiving line from first antenna 6₁₁ up to "n" 6_1N; information receiver output of the receiving system is connected to the nuclear quadrupole resonance signal radiation spectrum analysis unit through the filter unit and through the nuclear quadrupole resonance signal radiation spectrum processing unit; radiating part of the device for detecting emitters of nuclear quadrupole resonance of radiation is placed between two screening planes made in the form of truncated cylindrical planes.

EFFECT: technical result is automation of analysis of frequency properties of field of analyzed objects and their levels, and also the possibility of using the magnetic field emitter in the form of in-phase elementary magnetic emitters tuned to the frequency band of the excitation signals of the quadrupole echo.
