SENSOR OF SPECTROMETER OF DOUBLE NUCLEAR-ELECTRON RESONANCE

摘要

FIELD: magnetic radio spectroscopy, excitation and recording of signals in double nuclear-electron resonance spectrometers. SUBSTANCE: required technical result of invention lies in increased intensity of electron paramagnetic resonance-saturating field with maintenance of high sensitivity to signal of nuclear magnetic resonance recessary for double nuclear-electron resonance. Sensor includes device for saturation of signal of electron paramagnetic resonance manufactured in the form of spiral moderating system and resonance radio frequency circuit. Novelty of sensor consists in that it includes screen of nonmagnetic conductive material fabricated in the form of open cylindrical surface. Screen is positioned between devices for saturation of signal of electron paramagnetic resonance located inside screen and resonance radio frequency circuit. Variant in which open edges of screen are made with mutual overlapping and insulating spacer is placed between them is also feasible. EFFECT: expanded class of objects examined by method of double nuclear-electron resonance. 3 cl, 2 dwg
