Abstract
An RF receiver coil arrangement for the reception of measuring signals from a measuring sample in the measuring volume of an NMR spectrometer comprising an RF resonator having superconducting, inductively and capacitively acting conducting structures, which form resonant circuits, on planar substrate elements and which are disposed about the measuring sample, is characterized in that each individual current-carrying resonant circuit on the planar substrate element produces a magnetic field in the center of the measuring volume, which is parallel to the plane of the planar substrate element, on which the individual resonant circuit is located, wherein the deviation from parallelism, does not exceed 40 degrees. This introduces a new class of superconducting NMR resonators which better meet the technical requirements than those of prior art.
