    Abstract: An NMR system for measuring hydrogen loading status in a hydrogen reactor includes a reaction chamber having an interior reaction area. The system further includes a helical coil disposed around the interior reaction area. The helical coil is capable of generating an RF pulse and detecting free induction decay (FID) signals. The system further includes a magnet disposed around the helical coil. The magnet creates a uniform magnetic field substantially perpendicular to the RF pulse generated by the helical coil.

    Abstract: Nuclear magnetic resonance (NMR) logging tools may be configured for situation-dependent NMR logging operations by including two dissimilar coils that may function in four different modes of operation based on logging conditions including: a resistivity of the fluid, a diameter of the wellbore, a depth into the subterranean formation of the volume of investigation, or a combination thereof. For example, an NMR logging tool with a z-coil and a transversal coil may be useful in generating in a volume of investigation of a subterranean formation either (1) a transversal radiofrequency (RF) excitation with the transversal coil or (2) a quadrature RF excitation with both the z-coil and the transversal coil, where the choice of transversal or quadrature RF excitation is based on the logging conditions; and detecting an NMR signal from the subterranean formation with one of: (1) the transversal coil or (2) both the z-coil and the transversal coil.

    Abstract: Example devices and methods of MRI scanning are disclosed herein. In an example, an MRI scanning system may include a structure defining a bore within which a subject is to be positioned for scanning. The system may also include a magnet to generate a primary magnetic field within the bore parallel to a longitudinal axis of the bore, and a helical-antenna radio-frequency (RF) coil oriented along the longitudinal axis to surround the subject. In addition, the system may include an RF signal generator to drive the helical-antenna RF coil to generate a circularly polarized (CP) RF magnetic field perpendicular to the longitudinal axis, as well as an RF detector to detect a response signal generated by tissues of the subject in response to the CP RF magnetic field. Also included may be a computing system to create an image of the tissues of the subject based on the detected response signal.
