ABSTRACT:
In a coil system for an NMR spectrometer probe, a coil is wound around a cylindrical volume for containing the sample. The coil is used for producing an RF magnetic field in a direction perpendicular to the axis of the cylindrical volume. Leads from the coil connect it to an external circuit for executing the coil. Two leads are arranged to overlap each other adjacent the cylindrical volume with a dielectric substance sandwiched therebetween. The disclosed coil structure lowers inductance, raises Q value and enables higher tuning frequencies, enhances signal to noise ratios and sensitivity.
