摘要： An NMR system that enables multiplex resonance measurement includes a superconductivity reception coil, a transmission coil, and four electric current loops. The NMR system also includes an additional coil in which directions of currents that flow in an inner loop and an outer loop are opposite to each other. The additional coil and the transmission coil are arranged such that a direction of a high frequency magnetic field that is developed in the center of the additional coil when electricity is fed to the additional coil is substantially identical with a direction of a high frequency magnetic field that is developed in the center of the transmission coil when electricity is fed to the transmission coil. The electric current loop of the transmission coil is arranged substantially in the middle of the inner loop and the outer loop of the additional coil in which directions of electric currents that flow in the inner loop and the outer loop are opposite to each other.

摘要： An NMR probe movable through a bore hole (3) of a formation has a core (22) of a powdered high saturation flux density soft magnetic material with an elongated permanent magnet (21) which has a magnetic dipole moment. The structural geometry of the NMR probe facilitates the use of a powdered high saturation flux density soft magnetic material, which has a relatively low magnetic permeability in the core of the device.

摘要： Nuclear magnetic resonance (NMR) system and methods employing squashed (transversely-elongated) sample vessels (sample tubes or flow cells) for holding liquid NMR samples, and matching squashed saddle-shaped RF coils allow reducing sample and/or coil losses and increasing the RF circuit quality factors (Q). In a present implementation, the RF coils and sample vessels have rectangular cross-sections. Rounded (e.g. ellipsoidal) or other squashed cross-sections may also be used. The coil corresponding to the highest sample losses is positioned such that the magnetic field generated by the coil is along the major axis of the sample vessel. Squashed sample vessels may also be used with conventional circular coils, particularly for low-temperature measurements where sample losses dominate.

摘要： Ein Verfahren zur Beeinflussung des homogenen statischen Magnetfeldes B 0 in Richtung einer z-Achse in einer NMR-Apparatur, wobei Störungen auftreten, die durch supraleitende Komponenten von HF-Spulen zum Empfang von NMR-Signalen einer Probe in einem Messvolumen der NMR-Apparatur verursacht werden, wobei die supraleitenden Komponenten der HF-Spulen den HF-aktiven Bereich der Probe in z-Richtung überragen, und wobei die Störungen die z-Komponente des B 0 -Feldes im HF-aktiven Bereich der Probe betreffen, ist dadurch gekennzeichnet, dass die supraleitenden Komponenten der HF-Spulen einem zusätzlichen Magnetfeld ausgesetzt werden, das so stark ist, dass im Verlauf der Anwendung alle in der Nähe des HF-aktiven Bereichs der Probe angeordneten supraleitenden Strukturen in den supraleitenden Komponenten der HF-Spulen maximal magnetisiert werden und dadurch ihre bezüglich B 0 transversale Magnetisierung entlang der z-Achse einen im wesentlichen konstanten, von Null verschiedenen Wert annimmt. Die Erfindung betrifft weiterhin einen NMR-Resonator mit mindestens einer HF-Spule, wobei supraleitfähige Leiterstrukturen des NMR-Resonators im radialen Abstand von der Messprobe angeordnet sind, und wobei die supraleitfähigen Leiterstrukturen den HF-aktiven Teil der Messprobe in z-Richtung überragen, der dadurch gekennzeichnet ist, dass die supraleitfähigen Leiterstrukturen nach einer Anwendung eines zusätzlichen Magnetfeldes, das alle supraleitfähigen Leiterstrukturen maximal magnetisiert hat, eine bezüglich der Richtung von B 0 transversale Magnetisierung aufweisen, deren Wert entlang der z-Achse einen im wesentlichen konstanten, von Null verschiedenen Wert hat. Dadurch werden die NMR-relevanten Feldstörungen der HF-Spule eliminiert.
